Effect of in-vitro differentiated bone marrow mesenchymal stem cells in the treatment of peripheral nerve injury in rats

Peripheral nerves are more prone to damage during trauma. Though nerve grafts are used as an alternative method in treating it, the results are purely ambiguous. One such modern approach to treat peripheral nerve injury is bone marrow differentiated neuronal cells. Our present aim is to study the effect of in-vitro differentiated bone marrow mesenchymal stem cells (BMSCs) in the treatment of peripheral nerve injury in rats. Six weeks old rat weighing 80 gm was used for isolation and culture of BMSCs. The second passage cells were taken for neuronal differentiation. Flow cytometry and immunocytochemistry were performed with Anti goat IgG antibody indirectly conjugated with FITC to express nestin. In vitro differentiated BMSC along with PLGA Scaffold is injected into the site of peripheral nerve injury and the results were studied by ENMG, microdissection, and histopathology. The cells were expressed with Nestin goat polyclonal antibody. At the end of the second week, the rat reveals increased amplitude (8.3 mv) with decreased latency (0.8 ms) of the peripheral nerve. Micro dissection confirms the neuronal continuity of the injured peripheral nerve. Histopathology distinctly exhibit increased myelination and decreased endoneuronal space. In conclusion, neuronal differentiated BMSC, regenerate peripheral nerve injury faster than conventional methods and can be applied as an alternate therapy in peripheral nerve repair.

Comparison between isoflurane and sevoflurane in inhalation anesthesia: a prospective study

Inhalation of a gas anesthetic produces rapid induction of anesthesia without the need for intravenous drugs. Although it is specifically useful for patients who are afraid of injections or if their intravenous access is difficult, single-breath induction may also allow patients to wake up more quickly than intravenous induction drugs. The object of this study is to compare isoflurane and sevoflurane during inhalation in Libyan patients undergoing surgery in terms of side effects like blood pressure and heart rate changes and complications. Seventy- five patients were recruited in this study from different hospitals in Benghazi City, Libya (January to March, 2022) including Aljalaa Hospital and Alatfal Hospital, and data including side effects and complications were collected through data collection. Surgeries that used isoflurane, or sevoflurane or both inhalation gases for anesthesia were included in our data. While the surgeries which did not use any of these inhalation gases were excluded from our data. When we compared the side effects of using isoflurane with sevoflurane according to the age group, we found that hypotension is the most occurring side effect companies to the use of isoflurane in our adult population (28.6%) and in pediatrics (14.3%) but there was a low incidence of other side effects related to sevoflurane administration. Regarding to side effects related to the use of sevoflurane according to the age groups, 16 adult Libyan patients experienced no side effects (61.5%) compared to 10 children (38.5%). It can be concluded that both isoflurane and sevoflurane are suitable for daycare anesthesia. Sevoflurane might be an ideal drug for single-breath inhaled induction of anesthesia due to it has fewer side effects and complications.

A toxicological study of ecballium elaterium plant in mice

Ecbalium elaterium has a very violent effect on the body and has little use in modern herbalism. Little is known about the acute and chronic toxicities of ecbalium elaterium in human. This study aims to determine the acute toxicity (LD50) of fruit extract and another aerial part extract of the ecballium elaterium in experimental animals. Thus, male albino mice were divided into different groups each group consists of six mice receiving 40, 46, 52, 61, and 69 mg/kg of fruit extract of ecballium elaterium, respectively. Other groups were given 1000, 1412, 1995, 2818, and 3981 mg/kg of the areal part of ecballium elaterium extract, respectively. The LD50 in both treatments was determined by using the Spearman-Karber method. The LD50 of the fruit and aerial parts of ecballium were 55 mg/kg and 2112.5 mg/kg, respectively. The present findings showed significant weight loss after one month of treatment with 1400 mg/kg and 40 mg/Kg of fruit and aerial part extracts, respectively. The results indicated that the fruit extract is highly toxic as compared to the extract of the aerial parts.

Uric acid and glucose metabolism in uncomplicated libyan diabetic patients

Uric acid has increasingly been associated with insulin resistance, hyperinsulinemia, and type 2 diabetes mellitus. Diabetic patients who are hyperuricemic have a risk of developing diabetic complications. Pathogenesis of uric acid may decrease nitric oxide bioavailability in vascular smooth muscle, endothelial cells and direct scavenging of nitric oxide by uric acid. A decrease in endothelial nitric oxide production by uric acid has also been associated with endothelial dysfunction and insulin resistance. This study aims is to determine the relationship between uric acid and glucose levels in patients with type 2 diabetes mellitus. The study included 161 Libyan patients (67 males and 94 females) diagnosed with type 2 diabetes mellitus. Both levels of serum uric acid and hemoglobin A1c (HbA1c) were determined. The patients were divided into two groups. The controllable diabetic group with HbA1c of less than 06.0% and the uncontrollable diabetic group with HbA1c of more than 06.0%. Patients who are suffering from type 2 diabetes mellitus without complications were included whereas patients with smoking, alcoholism, nephrotic disease, malignancy, hepatitis, and renal failure or kidney disease were excluded. The mean and standard deviation of uric acid, HbA1c and Pearson correlation coefficient test were considered. In the controllable diabetic group, serum uric acid mean was found to be 4.807 ± 1.39 and HbA1c was found to be 5.032 ± 1.39. In the uncontrollable diabetic group, serum uric acid was 4.897 ± 1.66 and HbA1c was 8.396 ± 1.65. Uric acid level has significantly been correlated with HBA1C in controlled and uncontrolled diabetic patients (p < 0.05). In addition, the uric acid level was found to be higher in uncontrolled diabetic group than that in the controlled group (p < 0.05). A possible relationship between serum uric acid and incidence of type 2 diabetes mellitus was noted. Thus, uric acid can be used as a potential biomarker to indicate impaired glucose metabolism.

Serum electrolyte levels in libyan patients with type ii diabetes mellitus

The incidence of diabetes mellitus has increased globally making it a major public health concern. Diabetes mellitus is the most common metabolic disorder that causes an imbalance in the electrolytes which regulate essential metabolic mechanisms of the body. This study aimed to estimate the electrolyte levels in Libyan patients with type II diabetes mellitus and to investigate their relations to glycemic control and body mass index. A total of 122 Libyan subjects whose ages ranged between 35 years and 60 years for both sexes were included in this study, 77 patients were type II diabetic patients (37 males and 40 females) and 45 subjects were healthy individuals (23 males and 22 females) live in Tripoli area, Libya. The levels of blood glucose, HbA1c, sodium, potassium, chloride, magnesium and calcium were estimated in this study along with the measurement of body mass index, systolic and diastolic blood pressure. All the findings were statistically analyzed by one-way ANOVA test. Significant increases in glucose, HbA1c, potassium, chloride, calcium, blood pressure and BMI among diabetic patients were observed as compared to the healthy individuals. On the other hand, significant decreases in sodium and magnesium levels among the diabetic patients were observed as compared to the control group. In addition, significant alterations in all the biochemical parameters in uncontrolled diabetic patients as compared to the controlled diabetic patients, and in unhealthy weight diabetic patients as compared to the healthy weight patients. It is concluded that diabetes mellitus results in an imbalance of electrolytes. Poor glycemic control and obesity have adverse effects on electrolyte balance among diabetic Libyan patients. Good glycemic control, maintaining a healthy weight and regular evaluation of electrolytes among diabetics can reduce the fatalities associated with electrolyte rearrangements.

Effect of beetroot juice supplementation on the physical and biochemical profiles of induced metabolic syndrome in rat

Beetroot is vegetable containing phytochemical ingredients with potent antioxidant, hypoglycaemic and anti-inflammatory properties. It is key drivers in the pathophysiology of some metabolic syndromes. Its effect on the progress of induced metabolic syndrome has, however, hardly been investigated. Thus, this study aims to determine the effect of beetroot extract on various biophysical components of metabolic syndrome in rat. Following ethical approval, 50 Wister albino rats were used in this study and divided into three groups: Group A: rats were put on a high-fat-high-fructose (HFHF) diet; Group B: rats were put on an HFHF + fresh beetroot extract while group C: rats were the control group and were given a normal diet. The animals’ body weights and fasting blood sugar were taken fortnightly. Five rats from each group were then sacrificed at weeks 4, 8, 12 and 16 and the following parameters were measured: liver volume, fasting lipid profile, hepatic transaminases and blood platelet level. Compared to the HFHF group, beetroot supplementation resulted in a significant attenuation of overall weight gain (56.91% vs. 34.51%; p < 0> 0.05). Beetroot supplementation further ameliorated the thrombocytopenia caused by an HFHF. Beetroot juice supplementation attenuated the attendant effects of induced metabolic syndrome which might contribute towards averting the consequential cardiovascular sequel. Thus, lifestyle modification comprising beetroot intake as a dietary supplementation may alleviate metabolic syndrome and may offer a potential non-medical adjunct in the routine management of metabolic syndrome.

Evaluation of mineralized plasmatic matrix on augmentation of bone resorption

Bone resorption is created by different etiological factors, such as tumors, infections, and trauma. When defects are too large and healing is not possible in a spontaneous way, the defect is called a critical size defect, which is defined as the smallest size of an intra-osseous wound that will not heal spontaneously during the lifetime of the individual. This study was conducted to evaluate the use of a mineralized plasmatic matrix versus bone graft alone or in the augmentation of bony cavities in animals. Ten adult male dogs ranging in age from 12 months to 18 months with a mean weight of ten kilograms were used in this study. Bone cavities were made in the tibia of each animal. The upper holes were implanted with a bovine bone material substitute the medial holes were implanted with a mineralized plasmatic matrix and the lower holes were left free from any implant material acting as control. The dogs were euthanized at 2, 4, and 6 weeks and prepared for H and E stain and trichrome stain. The healing process of bone cavities implanted with mineralized plasmatic matrix was better compared to cavities filled with bone grafts and those left to heal spontaneously. Mineralized plasmatic matrix facilitates graft application, in its stabilization, and improves cell penetration into the graft.

Dosing in the neonatal intensive care unit

Over the years, pharmacy has developed from a simple floor stock system to a complex unit dose, I.V. additive, and clinical pharmacy program. This development would have never been possible without the support of the nursing, medical, and administrative staff. The support of obtained slowly by developing services that increase the pharmacist's credibility as a team member concerned with the pediatric and neonate patients. These services include a unit dose program, I.V. additive program, drug information services, and pharmacy medication program. One area in which pharmacist does not obtain a background from generalized training is the area of pediatric dosing. Pediatric pharmacists must learn in clinical practice the proper dosing of the pediatric patient and neonate patient. The dose must be checked periodically. In the premature or newborn infant, the pharmacist must consider the immature renal and hepatic function so that he/she does not overdose initially and then underdose as the infant grows and matures. Neonates are a special group of children, they are less than 30 days, and within this group preterm babies (that means less than 37 weeks). Determining the correct dose for drugs used to treat neonates is a critically vital factor. Prematurity affects kidney and liver function and the proper adjustment of drug doses is crucial [1]. The absence of drug level necessitates the adjustment of drug doses and the presence of qualified oriented dependable pharmacists. Drug doses are not numbers, or decimals used within the therapeutic range. Neonatal Intensive Care Unit (NICU) needs a system for the calculation and preparation of drugs [2].

Educational intervention on knowledge of hypertension and lifestyle/dietary modification among hypertensive patients attending a tertiary health facility in nigeria

Patients’ knowledge of hypertension and treatment has been found to affect health outcomes of hypertension. This study aimed to assess the impact of therapeutic patients’ education on knowledge of hypertension and lifestyle/dietary modification among hypertensive patients in Nigeria. The study was conducted among 317 hypertensive patients randomized into controlled and intervention groups (158 vs 159, respectively) between March 2021 and February 2022. Baseline knowledge of the patients was assessed and intervention was provided for the intervention group with a structured educational program at a baseline and six months. Descriptive data were presented with a frequency table in percentage while the chi-square test and univariate logistic regression were used to determine the association between categorical variables. Out of the total number of 318 patients, 275 completed the study (response rate: 86.8%) with 136 in the control group and 139 in the intervention group. The mean age of the patients was 59.5 (±12.5) and patients > 60 years (49.5%) were the most frequent age category. The baseline knowledge score of hypertension was 9.8 (±2.6) and 9.3 (±2.6) on a scale of 16 points in the control group and intervention group, respectively (P = 0.060) while at six months 11.9 (±2.3) vs 10.8 (±2.4) (P < 0.001) and 12 months 12.6 (±2.5) vs 9.5 (±2.0) (P < 0.001), respectively. Knowledge of lifestyle/dietary modification in the control group and intervention group at baseline was 7.0 (±2.1) and 6.6 (±2.0), respectively, while at six months 7.5 (±1.5) vs 9.9 (±1.3) (P < 0.001) and at 12 months 7.2 (±1.5) vs 10.4 (±1.2), respectively. Marital status, body mass index, and family history of hypertension were associated with knowledge of hypertension and lifestyle/dietary modification (P < 0.001). The educational intervention provided was found to be associated with a significant improvement in knowledge of hypertension and lifestyle/dietary modification. The marital status of the patients, body mass index and family history of hypertension influenced patients’ level of knowledge.

Evaluating the effects of insulin, metformin and glibenclamide on the pups’ prefrontal cortex and oxidative stress markers of streptozotocin-induced diabetic pregnant rats

There is an upsurge in gestational diabetes mellitus with many devastating consequences for the mother and developing fetus. Insulin therapy remains a mainstay. However, insulin is expensive and comes with the pain of multiple injections. Therefore, there is a need to explore commonly administered oral hypoglycemic agents to cater for the increasing gestational diabetes mellitus-associated neurological complications. This study assesses the effects of glibenclamide, metformin and insulin on the pups’ prefrontal cortex in diabetic pregnant rats. 35 sexually matured adult female rats weighing between 120 g and 160 g were used and assigned into five groups (A to E) of seven rats each group. Diabetes was induced by streptozotocin (45 mg/kg and 35 mg/kg; ip). Hyperglycemic rats were treated with insulin (1.0 UI daily), metformin (200 mg/kg/day) and glibenclamide (0.6 mg/kg/day). Body weight and blood glucose levels were evaluated. Rats were sacrificed at 18-day gestation, the pups were harvested, and their brains were processed for tissue oxidative stress markers and various histological examinations. Glibenclamide and metformin caused a significant blood glucose reduction at 37.9% and 40.7%, respectively, compared to the insulin group (33.09%). There was no significant difference in the body-organ ratio in rats treated with metformin when compared to rats treated with insulin. Metformin and glibenclamide had a significant increase in tissue glutathione reductase and a decrease in malondialdehyde compared with insulin and diabetic control groups. The pups’ prefrontal cortex showed degenerated neuronal cells in the diabetic control animals. The diabetic rats treated with metformin and glibenclamide showed improved pyramidal neurons compared with diabetic and insulin groups. This study suggests that metformin and glibenclamide glycemic control may prevent and improve antioxidant enzymes and reverse some neurotoxic effects caused by streptozotocin-induced diabetes in rats.

Influence of phoenix dactylifera leaf extract on doxorubicin-induced nephrotoxicity and hepatotoxicity in rats

The research into plant is used to search for new agents with pharmacological activities. This study seeks to evaluate the effects of the palm leaf methanolic extract against nephrotoxicity, hepatotoxicity, and weight loss induced by chemotherapeutic drug doxorubicin in a rat’s model. Five groups of rats (n= 4 in each group) were treated with or without doxorubicin (3.0 mg/kg/day, ip) and with palm leaf methanolic extract (400 mg/kg/day or 1200 mg/kg/day, po), followed by evaluation of renal and hepatic biochemical markers. The findings obtained indicated that palm leaf methanolic extract exerts protective effects against doxorubicin-induced nephrotoxicity and hepatotoxicity. Doxorubicin significantly elevated renal function markers, namely creatinine, uric acid and urea, however, these biomarkers remained within normal levels after treatment with palm leaf methanolic extract (400 mg/kg/day) as compared to the control group. Treating the rats with doxorubicin and palm leaf methanolic extract at doses 400 mg/kg/day and 1200 mg/kg/day, counteracts the doxorubicin-induced elevation of serum creatinine and uric acid compared to the doxorubicin group. Doxorubicin also significantly increased hepatic function tests namely alanine and aspartate aminotransferase, gamma-glutamyl transferase, and bilirubin as compared to the control group. In addition, treating the rats with palm leaf methanolic extract doses and doxorubicin caused a significant decrease in the serum levels of hepatic markers compared to the doxorubicin group. Doxorubicin treatment resulted in a weight loss of 34.1%, the weight loss caused by doxorubicin was prevented by treating the rats with the extract at 1200 mg/kg/day as compared to their baseline body weight. Thus, the results of the current study suggest that the active constituents present in the palm leaf methanolic extract have a protective effect against hepatotoxicity, nephrotoxicity and weight loss-induced by doxorubicin.

Prevalence of acute infectious hepatitis in eastern libyan pediatrics

Viral hepatitis is one of the main public health concerns around the world. Even though infection management techniques have been implemented over the last few decades, eradication or significant reduction has remained a mystery. The purpose of this study is to look into the prevalence of acute infectious hepatitis in the East of Libya and how the type of virus, age, gender, clinical manifestations, and outcome are related. This is a hospital-based retrospective study. The data on the frequency and distribution of viral hepatitis based on age, gender, seasonal, clinical, and ultrasound findings, and the outcomes during a period of two years from January 2020 to December 2021 were collected and analyzed. Of the 0.39% (72 cases) of total hospital admissions (18340) under the age of 15 years old for acute infectious hepatitis patients, the most common age group was 5-12 years (79.6%). Winter accounted for 41.6% of all the cases. Females made up 65.3% of the cases. Jaundice was the most prevalent presentation (87.5%). Hepatomegaly was seen in 83.3% of the patients. Most of the cases have mild hyperbilirubinemia (5-9 mg/dL, 75.0%). Approximately 1/5th of the patients' serum glutamic-oxaloacetic transaminase (SGPT), and nearly 1/3rd of the patients' SGPT levels were in the range of 1000-2000. One patient's hepatitis C was positive, one patient's hepatitis B was positive, and 97.2% were positive for hepatitis A. 88.8% of the individuals recovered without complications, whereas 11.1% showed symptoms of hepatic failure but recovered. The present study indicates that acute hepatitis A is more prevalent, especially in the winter. Those who are females and 5-12 years of age were more affected by acute viral hepatitis in Libya.

Jobelyn® ameliorates anxiety response and oxido-inflammatory markers induced by tramadol use and discontinuation in rats

Jobelyn® is a multi-functional natural dietary supplement made from Sorghum bicolour with very high anti-oxidant and anti-inflammatory capacities. The study investigated the role of Jobelyn® in the attenuation of oxido-inflammatory markers induced by tramadol use, abuse and discontinuation over 17 days in rats. The experimental observational study was carried out using male adult albino rats weighing between 100 and 170 g. The experimental design involved five groups. Rats were randomly divided into groups of five, consisting of group 1 (normal control rats), and group 2 (rats treated with tramadol at 40 mg/kg/day) were administered for 10 days and discontinued for seven days. Group 3 administered incremental doses of tramadol from 40 mg/kg/day to 100 mg/kg/day over 10 days and discontinued for seven days. A similar treatment protocol was administered for group 4 and group 5 but were treated with Jobelyn® at a dose of 200 mg/kg/day at the discontinuation phases for seven days. Behavioral assessments (elevated plus maze model of anxiety and open field model of locomotor activity) and biomarkers of oxido-inflammatory stress were assessed. Tramadol-treated groups had significant anxiety responses and locomotory deficits in comparison to the control group. Tramadol-treated groups had significant elevations of nitrites and malondehyde and reduced enzymatic markers such as catalase, glutathione, reduced glutathione, superoxide dismutase, G-s-transferase, glutamic acid decarboxylase and increased activity of acetylcholinesterase when compared to control group. Administration of Jobelyn® attenuated the responses and ameliorated the oxido-inflammatory biomarkers similar to levels in control group. Tramadol induces oxido-inflammatory stress markers in the prefrontal, striatum and hippocampus in rats. Anxiety and locomotory behavioral actions on tramadol treatment were elevated despite discontinuation for seven days. Thus, Jobelyn® at 200 mg/kg/day ameliorated oxido-inflammatory markers induced by tramadol and decreased anxiety responses in albino rats.

Effect of resveratrol on total protein and albumin in type 2 diabetes wound healing in rats

Resveratrol, a polyphenol predominantly present in red grapes, has attracted interest due to its possible health advantages. The anti-inflammatory, antioxidant, and vasodilatory properties of this substance indicate that it may have a beneficial effect on wound healing in individuals with diabetes mellitus. This study aims to determine the role of resveratrol on type 2 diabetic wound healing on total protein and albumin levels in rats. 20 male adult Albino Wistar rats were rendered diabetic using a high-fat diet and an alloxan injection (120 mg/kg). The rats were grouped into four: non-diabetic control group (negative control), diabetic control group (positive control), diabetic treatment group 1 (resveratrol: 10 mg/kg) and diabetic treatment group 2 (resveratrol: 20 mg/kg). Excisional wounds were created and monitored for wound closure over a defined treatment period of 14 days. Studies were conducted and expressed using physical and biochemical indices. The data demonstrated wound healing activities via biochemical indices, and histological and macroscopic methods. There was a difference in fasting blood glucose between the diabetic control group with the treatment groups. There was a difference between the diabetic control group compared to the group treated with resveratrol 10 mg/kg and 20 mg/kg in the weight of the rats. There was no significant acceleration in total albumin and globulin levels in the diabetic wounded group treated with resveratrol (10 mg and 20 mg). The results suggest that resveratrol treatment does not affect on total albumin and globulin levels in diabetic rats.

Pharmacognostic and preliminary phytochemical investigation of aerial parts of centella asiatica linn

In the Indo-Pak subcontinent, the traditional systems of medicine, both Ayurvedic and Unani, are primarily based on herbs and herb-based preparation for therapy. Therefore, the importance of the herbal identification process remains critical in achieving the desired and successful therapeutic effect. To support the manufacturers and practitioners of both systems, many herbs are still collected from wild sources, as herbal farming is not very developed in this part of the world. During a survey program conducted in different areas of Pakistan, significant lacks and gaps were noted to be present in the identification & characterization of herbs, which needs to be addressed and fulfilled as many species look alike apparently or physically but have different biological or pharmacological activity. Based on this objective and approach, Centella asiatica was selected for the pharmacognostic and preliminary phytochemical investigation to establish a better correlation and to provide useful methods in its identification as the use of Centella asiatica is very common in Pakistan and other South Asian countries for CNS disorders therapy. Therefore, this study aimed to develop & report some and rapid identification methods for Centella asiatica. The present study includes physical, physicochemical, preliminary phytochemical and fluorescence analysis. For the first time, in the present study, NIR and FT-IR spectra of Centella asiatica have been reported for identification. The findings of the present study are quite promising and can be helpful for the manufacturers and researchers in the identification and development of Centella asiatica-based new drugs or formulations.
