The purpose of the experiment is an investigate the association of walnut oil with lipid profiles, glucose as well as total proteins and assessment its side effect on some sensitive organs such as the liver and spleen tissues. The experiment divided into two main groups are treated group with walnut oil and the control group, where the former divided into two subgroups 0.25 and 0.5 ml of oil per each. We found a statistically non-significant difference between treated and control groups (for total protein, lipid profile, and glucose). There was no change in total protein, but cholesterol decreased by 0.25 ml but a little increased by 0.5 ml. HDL was increased for the treated group. While on 0.25 ml LDL decreased in treated animals, on another hand no change for 0.5 ml. Also, no change for VLDL between treated and control. The only triglyceride was increased but non-significant for the treated group compared with the control. Both doses decreased in treated animals for glucose. We also found an increase in whole-body weight and on sensitive organs such as the liver and spleen. Even no change in a histological study for the mentioned organs. The conclusion: By walnut oil, all parameters have changed despite the treated group was normal without any induced diseases. So, recommended the researchers induce the disorders in the liver and assessment the extracted oil on the lipid profile.

INTRODUCTION: Hypothyroidism is non-curable common endocrine disorder in which the thyroid gland is unable to produce enough thyroid hormone. Present with a number of symptoms, Having a low level of thyroid hormone affects our whole body. Untreated hypothyroidism can be the cause of raised cholesterol levels. Many study have shown association between hypothyroidism and lipid profile. In this study, we evaluate the mean lipid profile status in subclinical hypothyroidism and hypothyroid patients.  MATERIAL AND METHODS: A hospital based retrospective study done from the record card maintained in Alka Hospital, Jawalakhel. Total number of participants were 215. Out of which 73 had overt hypothyroidism, 92 had subclinical hypothyroidism and 50 were taken as control. SPSS version 20 was used for data analysis.  RESULTS: The level of LDL, TG and TC was significantly higher in case of overt hypothyroidism as compared to control group, but no significant difference was found in subclinical hypothyroidism and control group. TG level was significantly lower in subclinical hypothyroidism cases.  CONCLUSION: Elevated HDL, LDL & TC is seen in overt hypothyroid patients. It is important to screen for lipid profile in hypothyroid patients.DOI: http://dx.doi.org/10.3126/jucms.v2i4.12065Journal of Universal College of Medical Sciences (2014) Vol.02 No.04 Issue 08Page: 33-36

Aims: Damage to liver tissue and its dysfunction is very important and if left untreated, it can cause serious problems and even death. In this study, we aimed to investigate the effects of the hydroalcoholic extracts of Linum usitatissimum and Rosa damascena on liver enzymes, total protein, bilirubin, albumin, and serum glucose levels. Materials and Methods: This is a non-randomized clinical trial conducted on 42 male rats divided into 6 groups; control group (group 1) received only sufficient water and food, groups 1 and 2 received 300 and 500 mg/ kgB.W Linum usitatissimum extract, groups 3 and 4 received 500 and 1000 mg/ kgB.W Rosa damascena, and group 6 received 100 mg/ kgB.W Linum usitatissimum plus 250 mg/ kgB.W Rosa damascena extracts intraperitoneally for 28 days. After the last injection, the rats were weighed and their blood samples were collected. The study parameters were measured using a colorimetric method by a spectrophotometer, and then were analyzed using ANOVA and Tukey’s test in SPSS V. 25 at a significance level of P<0.05. Findings: There was no significant difference between alanine aminotransferase, alkaline phosphatase, total and direct bilirubin levels in the control group in comparison with other groups (P>0.05). In the groups received Rosa damascena extract, there was a significant difference between total protein and albumin levels compared to the control group (P<0.05). Moreover, there was a significant difference between serum glucose and aspartate aminotransferase in the control group compared to other groups (P<0.05). Conclusion: Linum usitatissimum and Rosa damascena have no negative effect on the liver function. The probability of diarrhea occurrence and the possible effects on the total protein and serum albumin after using Rosa damascena, and the effects of different doses of Linum usitatissimum on the glucose levels should be taken into account.

K Depletion

The responses of whole body, skeletal muscle, and plasma to oral K loading were studied in K-depleted male rats. Potassium depletion was induced by feeding the rats a K-deficient diet for 4 wk and injecting deoxycorticosterone acetate during the first week. After 4 wk, the rats were growth retarded and hypokalemic (1.9 mmol/l plasma) and had low whole-body and muscle K content, 188 +/- 27 and 276 +/- 19 mmol/kg fat-free dried tissue (FFDT), respectively, compared with 296 +/- 10 and 454 +/- 13 mmol/kg FFDT for the control group. Sodium and water retention also occurred in the K-deficient group. After K depletion, the rats were divided into four groups and received either 0, 1, 2, or 3 intragastric doses of 10 mmol KCl/kg at 8-h intervals. The rats were killed 8 h after the last dose. Control rats were treated similarly. K-depleted and control rats responded differently to K loading. In the normal rats, plasma K remained at 5.0 +/- 0.5 mmol/l, muscle K increased to 502 +/- 24 mmol/kg, and muscle K/N ratio increased from 3.0 to 3.4 mmol/g. In the K-depleted rats, plasma K increased to 7.2 +/- 0.7 mmol/l, muscle K increased to 453 +/- 50 mmol/kg, and muscle K/N ratio increased from 1.8 to 3.1 mmol/g. These data indicate that the capacity of the muscles to accumulate K was impaired after severe K depletion and caused elevated plasma K levels when repletion was complete.

Abstract Abstract 4226 Patients with childhood ALL achieve long-term disease-free survival, making reducing complications of therapy of major concerns. The aim of this study was to assess the prevalence and degree of neurocognitive dysfunction in survivors of childhood ALL treated with different protocols and the effect of time since end of chemotherapy. Patients and methods: A cross-sectional study including 60 ALL survivors aged 5–16 years at enrollment; 2–9 years at diagnosis, CNS1, treated through 1998–2008 and regularly followed up in childhood cancer survivors clinic;. They were compared to 20 healthy age and sex matched controls. Grade of school, scholastic achievement in the previous year were reported followed by revision of hospital records including type and risk of ALL, protocol of treatment, number, type and dose of intrathecal chemotherapy, number and doses of high dose I.V methotrexate, data of cranial radiotherapy. Three different protocols were applied to these patients according to the time of diagnosis, patients diagnosed between January 1998 to December 2000 were treated with Modified BFM 83. Those diagnosed between January 2001 to June2004 were treated with BFM 90 protocol, and those diagnosed From July 2004 to June 2008 were treated with CCG 1991 for standard risk and CCG 1961 for high risk patients.Neurocognitive functions were tested using Wechsler Intelligence Scale for Children,Benton visual retention (BVR) test and Trail making test (part A and B were done. MRI Brain was performed to the patients and control group using diffusion weighed images and diffusion tensor magnetic resonance imaging (DTI). Results: Survivors treated with CCG protocol showed a significant decrease in all cognitive tests results compared to control (p<0.05). Survivors treated with BFM 90 protocol had a significant lower total IQ, verbal IQ, TMT-partA, compared to both control and survivors treated with Modified BFM 83, and a significant decrease in performance IQ, BVRT and TMT-partB compared to control only. No significant difference between results of cognitive tests in survivors treated with Modified BFM 83 and control group. Both left and right frontal cortex apparent diffusion coefficient (ADC) was significantly higher in CCG(.88±.060.91±.028) treated group compared to control(.695±.0018.684±.0018), BFM 90(.79±.071.76±.048) and modified BFM 83(.76±.030.83±.023×10&minus;3mm2/s) groups (p<0.05) yet a significant decrease in FA of right frontal cortex only in CCG (.250±.039)treated group compared to control(.684±.0018), BFM 90(.450±.042) and Modified BFM 83(.41±.028) groups(p<0.05). FA of right frontal, was significantly lower in BFM 90 and Modified BFM 83 treated group compared to control group. No significant correlation was found between cognitive tests results with age at diagnosis, time since the end of therapy, total number of intrathecal injections, age at radiotherapy treatment, dose and time of radiotherapy. Cognitive tests didn’t differ between survivors treated with triple intrathecal therapy(ITTT) compared to those treated with intrathecal methotrexate, yet significant decrease in FA of right hippocampus in survivors who received ITTT compared to survivors treated with intrathecal monotherapy, Conclusion: Neurocognitive dysfunction was a common sequelae of childhood ALL treatment. It was more related to protocol of therapy rather than the duration of follow-up since end of chemotherapy. Frontal lobe FA may be a clinically useful biomarker for the assessment of neurotoxicity in post-treatment childhood ALL survivors. Disclosures: No relevant conflicts of interest to declare.

The aim of this research was to investigate the effect of vibration applications on muscle strength and balance. As the subjects to the research, nineteen male sport science students (age: 21.45&plusmn;2.16 years, height: 177.55&plusmn;7.24 cm, body mass: 71.62&plusmn;11.02 kg) voluntarily participated in the study. The students were exposed to vibration in squat exercise position before they were exposed to vibration at 25Hz, 50Hz frequency and control (no-vibration) on three different application days. Before and after the vibration exposure, jump tests and balance tests were administered right after the 5th, 10th and 15th min in the wake of the vibration. A statistically significant difference was found in active and squat jump heights administered following the 25Hz and 50 Hz frequency applications (p&le;0.05). No significant differences were found in the jump heights in control group (p&gt;0.05). While there was no significant difference found in balance tests performed after 25Hz and 50Hz vibration applications (p&gt;0.05), a significant difference was found after the control application (p&le;0.05). As a result, there was an increase in jump heights following the acute vibration application however, no change was seen in balance scores. Practicing acute vibration applications can be recommended to increase jump height especially before the competitions and applications.

Liver disease remains a significant global health problem. Increased caffeine consumption has been associated with a lower prevalence of chronic liver disease. This study aimed to investigate the modifying effects of caffeine on liver injury induced by thioacetamide (TAA) administration in male rats and the possible underlying mechanisms. Forty adult male rats were equally classified into four groups: control group, received only tap water; caffeine-treated group, received caffeine (37.5 mg/kg per day); TAA-treated group, received intraperitoneal (i.p.) TAA (200 mg/kg b.w.) twice a week; and caffeine + TAA-treated group, received combined TAA and caffeine in the same previous doses. After eight weeks of treatment, blood samples were collected for biochemical analysis and liver specimens were prepared for histological and immunohistochemical studies and for assessment of oxidative stress. TAA induced liver toxicity with elevated liver enzymes and histological alterations, fatty changes, apoptosis, and fibrosis evidenced by increased immunohistochemical reaction to matrix metalloproteinase-9 (MMP-9) and collagen type IV in hepatocytes. Also, the levels of pro-inflammatory cytokines (TNF-α, IL-1β, and IL-6) in serum were significantly elevated. Co-treatment with caffeine and TAA restored normal liver structure and function. Caffeine provided an anti-fibrogenic, anti-inflammatory, and antioxidant effect that was associated with recovery of hepatic histological and functional alterations from TAA-induced hepatotoxicity.

Myocardial infarction (MI) is a common cause of death due to interrupted blood supply to the heart. Roselle calyx (Hibiscus sabdariffa Linn.) is rich in polyphenols and has a potential in alleviating the risk of cardiovascular disease through its antioxidant activity. This study was aimed to investigate the effects of Hibiscus sabdariffa Linn. or roselle polyphenol-rich extract (HPE) supplementation in oxidative stress and cardiac injury biomarkers as well as cardiac histological changes following isoprenaline (ISO)-induced myocardial infarction (MI). Twenty-one male rats were randomly divided into three groups: control, MI, and HPE+MI. Normal saline or HPE (20 mg/kg BW) was given to MI and HPE+MI groups, respectively, for 14 consecutive days via force feeding. On the 15th and 16th day, 85 mg/kg body weight of ISO was administered subcutaneously to induce MI. Control group was only given normal saline throughout this 16-day duration of study. The results showed that HPE reduced the oxidative stress markers malondialdehyde (MDA) and nitrite oxide (NO) in HPE+MI group when compared with MI group (p<0.05) while increased reduced glutathione (GSH) level reflexes the improvement in antioxidant status. Cardiac injury biomarkers analysis showed no significant difference in HPE+MI group when compared to MI group. Histological study showed that HPE managed to reduce cardiac muscle fibre damage and infiltration of inflammatory cells in ISO-induced MI rats. In conclusion, HPE has the potential in protecting the heart against ISO-induced MI by reducing the oxidative stress and increasing antioxidant status.

AbstractOverall reproductive performance and associated periparturient disorders were monitored in a herd of British Friesian cross dairy cows from September 1987 to August 1988. Pregnancy diagnosis and cyclical status of the herd was determined by palpation of the ovaries per rectum. A total of 49 (110) cows were randomly treated with Sepia 200c either on day 14(19) or 21 days (30) postpartum.Statistical analysis of the results was based on the differences between the control and combined Sepia-treated groups. Although there were significant differences in the proportion of heifers calving in each group, there was no significant difference in periparturient disorders or during the pre-service period.However, in the Sepia Group that held a lower proportion of heifers, a significant difference was found in the conception rate to 1st service (47%), the percentage of cows in calf (90%) and total culling rate (10%) compared to the Control Group (26%, 72% and 28% respectively). A reduction (non significant) was found between the Sepia and Control services to conception (0.2), calving to conception interval (5 days) and calving index (2 days).The results of this pilot study appear to demonstrate a difference in effect between the Sepia-treated Group and Control Group. The study has been extended to treat a larger number of dairy cows to examine the reproducibility of these results.

Some people in different parts of Iran use burned mantles as a wound healing medicine. To perform surface area measurement, twenty rats were divided randomly into two groups of 10 animals each. The 1st group received topical burned radioactive lantern mantle powder at 1st-3rd day after making excision wounds. The 2nd group received non-radioactive lantern mantle powder. For histological study, 36 male rats randomly divided into two groups of 18 animals each. Full thickness excision wound (314±31.4 mm2) was made on the dorsal neck in all animals after inducing general anesthesia. For the first 3 days, cases received topical application of the radioactive lantern mantle powder. Finally, to measure the tensile strength, an incision was made on the dorsal neck of the rats. Surface area measurement of the wounds showed a progressive surface reduction in both groups. Histological study showed a significant statistically difference between cases and controls with respect to fibrinoid necrosis and neutrophilic exudate at the days 3 and 14. Considering the existence of granulation tissue, a significant difference was observed between case and control groups at days 3 and 7. Tensile strength study showed no significant difference between the cases and controls until 30 days after excision.

Abstract Effects of cottonseed flour in male and female rats’ fertility based on hormonal and histomorphometry changes were studied. Sixty-four Sprague-Dawley adult male and female rats were randomly divided into control and treatment groups. Treatment group was received diets containing cottonseed flour for 35 days. Control group was given standard rat food. Body and testis weights, epididymis semen evaluation indices and serum sex steroid hormones were determined. Histomorphometry alterations of testes and ovary were evaluated. Then, normal female and male rats were mated by rats in both groups and after 35 days, number of pups was measured. However, there was no significant difference in whole body and testes weights, sperm concentration and viability between the control and treatment groups, respectively. Moreover, sperm motility in the treatment rats was significantly lower than the control group. Serum hormones alterations were not significant, but histomorphometry evaluations of testes showed significant changes in the testis structures after chronic consumption of cottonseed flour. In the female rats, body weight did not have significant difference between the treatment and control groups. Histomorphometry data in female ovary showed significant reduction of primary follicle volume and number in the treatment group against control. Follicle stimulating hormone showed insignificant reduction in the treatment group. Number of pups was significantly reduced in the female rats fed by cottonseed flour. Cottonseed flour in rat diet had adverse effects on rat reproduction. Therefore, it can be used as an efficient product for control of the rat population as a natural rodenticide agent.
