Aim: To evaluate the effects of alcohol on the microscopic morphology of the exocrine pancreas and blood serum amylase and to explored that if vitamin E has a protective role against alcohol-induced damage in the pancreas of rabbits. Study design: Analytical experimental study Place and duration of study: Departments of Anatomy, Pathology and Pharmacology in Peshawar Medical College Pakistan from 1st January 2019 to 30th June 2019. Methodology: Eighteen healthy adult male domestic rabbits weighing 1-1.5 kg were chosen (oryctolaguscuniculus). The control group A received proper food and normal saline as drinking water, experimental group B received proper diet and 30 percent ethanol solution (30ml/kg/day) orally daily with normal saline, and experimental group C received proper diet, 30 percent ethanol solution (30ml/kg/day), vitamin E (50mg/kg/day) orally daily with normal saline. Each rabbit's blood was taken for serum amylase. Morphology of acinar cells included: 1) number of cells, (10 acini/field, 2) size of acini, 3) size of acinar cells, and 4) size of acinar nuclei. Results: Normal value of serum amylase in rabbits was found. The difference in serum amylase levels between the control and experimental groups for both E4 and E8 animals was not statistically significant. There was no significant difference in the number of pancreatic acinar cells, size of pancreatic acini, the pancreatic acinar cell size, and pancreatic acinar cells nuclear size in the control and experimental groups for both E4 and E8 animals. Conclusion: Alcohol consumption had no influence on the histomorphology of the rabbits' pancreatic acini in a short period (4-8 weeks). No significant variation was noted in the pancreatic acinar cells count & size, pancreatic acinar cells nuclear count and size, and pancreatic acini size. Therefore, protective role of vitamin E was not usefully identified.

Background: Sleep disorders, particularly insomnia, represent a significant health concern in medical education. Neuroticism, characterized by emotional instability and stress reactivity, shows cross-sectional associations with sleep disturbances in healthcare trainees. Limited research examines these relationships among South Asian medical students. This cross-sectional study investigated insomnia symptom prevalence, personality correlates, and environmental factors among Pakistani medical students. Methods: We conducted a cross-sectional study among 364 undergraduate medical and dental students in Peshawar, Pakistan (June–November 2024). Data collection occurred during examination months. Data collection employed validated instruments: the Insomnia Severity Index (ISI) and the NEO Five-Factor Inventory neuroticism subscale (NEO-FFI-12). Statistical analyses included Pearson correlations, chi-square tests, and multivariate regression with interaction terms. Results: Among 364 participants (mean age 21.3 ± 2.3 years, 52.2% female), 47.0% reported severe insomnia symptoms (ISI 22–28), with 89.0% experiencing at least subthreshold symptoms (ISI ≥ 8) during the 2-week assessment period. These prevalence rates reflect symptom severity over a 2-week period during examination months and do not represent clinical diagnoses of chronic insomnia disorder, which requires ≥3 months of symptoms with clinical confirmation. High neuroticism (NEO-FFI ≥ 37) characterized 59.8% of students. Multivariate regression revealed a robust cross-sectional association between neuroticism and insomnia symptom severity (β = 0.239, 95% CI [0.173, 0.305], standardized β = 0.342, p < 0.001) and may reflect measurement during peak examination stress rather than stable trait-outcome relationships. Hostel residents showed non-significantly higher clinical insomnia prevalence than day scholars (75.9% vs. 67.5%, p = 0.081). Clinical-year students demonstrated significantly lower insomnia severity than pre-clinical students (β = −1.271, p < 0.001), a finding that contradicts assumptions about increasing stress through training progression. The neuroticism × living arrangement interaction was non-significant (p = 0.118); however, post hoc power analysis indicated the study was underpowered to detect small moderation effects, making this finding inconclusive. Conclusions: This study documents high insomnia symptom severity during a 2-week assessment period in Pakistani medical students, with a robust cross-sectional association with neuroticism. However, these findings must be interpreted within the constraints of the cross-sectional design, which cannot establish temporal precedence or causality between neuroticism and insomnia symptoms. These symptom prevalence rates likely reflect a combination of chronic sleep disorders and transient examination-related stress. Living arrangements showed small, non-significant associations with insomnia. The observed association between neuroticism and insomnia may be partially mediated or confounded by unmeasured variables, including academic stress, psychiatric comorbidities, substance use, and other sleep disorders. Findings suggest potential benefits from interventions addressing cognitive-emotional factors, though comprehensive diagnostic assessment is needed to distinguish chronic insomnia disorder from transient, stress-related sleep difficulties. Longitudinal research with objective sleep measures, structured psychiatric assessment, and systematic confounder evaluation is essential to establish causal relationships and intervention efficacy in this population.

Objective: To determine the hepatotoxic effects induced by cypermethrin. The study also attempts to evaluate the hepatoprotective efficacy of Nigella sativa oil against hepatotoxicity produced by cypermethrin. Study Design: Experimental study. Setting: Department of Anatomy, Pharmacology, and Pathology of Peshawar Medical College and Animal house of PCSIR Laboratories Complex, Peshawar. Period: May 2023 to Dec 2023. Methods: Animals were divided into two groups: Control (Group A) and Experimental (Group B). The Experimental group (Group B) is divided into two subgroups Group B-I and Group B-II. Forty-two male Sprague Dawley rats were randomly assigned to three groups of fourteen rats each in order to conduct an experimental investigation. Group A served as a control group. Cypermethrin (5.5mg/kg‾¹ body weight) per day dissolved in corn oil was administered orally to Group B-I. Cypermethrin (5.5 mg/kg‾¹ body weight) per day orally and (1ml/kg‾¹ body weight) per day of Nigella sativa oil were given to group B-II. Liver obtained from these groups were fixed for histological studies under light microscopy. Liver tissues of the cypermethrin-treated animals showed leucocytic infiltration, hydropic alterations such as ballooning degeneration and focal lytic (spotty) liver necrosis. Results: After four weeks of treatment with cypermethrin demonstrated significant liver damage in group B-I animals. In group B-II Nigella sativa oil significantly reduced hepatotoxicity and induced regenerative changes. Nigella sativa oil demonstrated protection against the cypermethrin and preserved the normal histological architecture of the liver. Conclusion: Cypermethrin had a hepatotoxic potential and caused hepatotoxicity in liver, as evidenced by the histological changes in the liver tissue. However, the study also found that Nigella sativa oil showed a better hepatoprotective effect, as it was able to effectively reverse the liver damage caused by both cypermethrin.

In this study, we aimed to assess the topographic anatomy and clinical impact of the vascular foramen on the trochlear groove of adult human dry femora. The incidence, shape, size, and location of the foramen present on the trochlear groove of the distal femur were studied using 33 adult human dry femora of unknown age and gender at the Department of Anatomy at Nowshera Medical College, Nowshera, Pakistan. Using a divider and scale, the incidence and structure of the vascular foramen in the trochlear groove were examined and its position in relation to the trochlear groove's upper and lower articulating edges was recorded. Out of 33 femora, 20 (60.6%) were right-sided and 13 (39.4%) were left-sided. All the foramina had round morphometry. In each of the 33 adult human dry femora, 15 (45.5%) had a single trochlear vascular foramen. One solitary trochlear vascular foramen was found in eight (53.3%) of the left femora and seven (46.7%) of the right femora. The diameter of each trochlear vascular foramina was about 2.5-4.5 mm with a mean diameter of 3.5 mm. Trochlear groove upper margin and foramen were 1.75-2.5 cm apart, whereas the lower margin was 0.5-01 cm apart. On average, foramen was 2.2 cm away from the upper margin, and 0.8 cm away from the lower margin. In the midline, nine (60%) trochlear vascular foramina were found, with five (55.5%) resting on the trochlear groove lower margin, and four (44.5%) lying mid-way at varying places from the upper and lower margins. The left of the centerline had six (40%) of the trochlear vascular foramen, whereas no trochlear vascular foramen was seen on the right side of the midline. Based on our findings, a significant segment of our population has trochlear vascular foramen present on the trochlear groove as the rate of occurrence of this was found to be 45.5%. The trochlear groove center has the most foramen, accounting for 60% of all the foramen.
