Objective. Studying correlative changes of Th1/Th2 (Th, Helper T cells) related factor Interferon-γ (IFN-γ) and Interleukin-4 (IL-4) in the progression of radiation pneumonia (RP) rats and the efficacy of Shashen-Maidong decoction on these indexes to explore the immune mechanism of the decoction on the prevention and treatment of RP. Methods. Male 60 Sprague-Dawley (SD) rats were randomly divided into four groups. In addition to the normal control group taking saline, the other rats were set up RP model treated with Shashen-Maidong decoction or dexamethasone (DXM), respectively. The IFN-γ and IL-4 concentrations in serum and bronchoalveolar lavage fluid (BALF) of rats were tested in the 2nd and 4th week after radiation, and the relative ratio of IFN-γ/IL-4 was calculated. Results. (1) There was significant difference of serum IL-4 concentrations in group B (p<0.01) and extreme difference in groups C and D (p<0.001) compared with group A in 4th week. Compared with group D, IL-4 concentrations in group B increased significantly in both 2nd and 4th week (p<0.01). Group B had significantly decreased IFN-γ concentrations in BALF (p<0.001) compared with group D in the 4th week. And IFN-γ concentrations in BALF in group B were increased compared with group C in the 4th week (p<0.05). (2) There was no difference of the relative ratio of IFN-γ/IL-4 at each time in groups B and A for both serum and BALF, while the ratios in groups C and D in 4th week in BALF were increased (p<0.05) compared to group A. Conclusion. Shashen-Maidong decoction can improve the immune function of RP rats by increasing IFN-γ concentration and decreasing IL-4 concentration, possibly by increasing the relative ratio of IFN-γ/IL-4 to regulate the immune imbalance of Th1/Th2.

The objective of this work was to investigate the effect of orally administered genistein on the pharmacokinetics of imatinib and N-desmethyl imatinib in rats. Twenty-five healthy male SD (Sprague-Dawley) rats were randomly divided into five groups: A group (control group), B group (multiple dose of 100 mg/kg genistein for consecutive 15 days), C group (multiple dose of 50 mg/kg genistein for consecutive 15 days), D group (a single dose of 100 mg/kg genistein), and E group (a single dose of 50 mg/kg genistein). A single dose of imatinib is administered orally 30 min after administration of genistein (100 mg/kg or 50 mg/kg). The pharmacokinetic parameters of imatinib and N-desmethyl imatinib were calculated by DAS 3.0 software. The multiple dose of 100 mg/kg or 50 mg/kg genistein significantly (P<0.05) decreased theAUC0-tandCmaxof imatinib.AUC0-tand theCmaxof N-desmethyl imatinib were also increased, but without any significant difference. However, the single dose of 100 mg/kg or 50 mg/kg genistein has no effect on the pharmacokinetics of imatinib and N-desmethyl imatinib. Those results indicated that multiple dose of genistein (100 mg/kg or 50 mg/kg) induces the metabolism of imatinib, while single dose of genistein has no effect.

Abstract Background: The study sought to investigate the effects of dexmedetomidine on cognitive function after anesthesia and to examine its actual mechanism. Methods: A total of 48 rats were randomly divided into model Groups A, B, C, or D. Rats in Groups A, B, and C received a hypodermic injection of D-gal with a concentration of 1,000 mg·kg−1·d−1 respectively for 1 week. Group D received the same volume of saline. The Morris water maze (MWM) test was performed within 6 days of the injection. After the behavior test, Group A received an inhalation dose of 2% sevoflurane. Group B received an inhalation dose of 2% sevoflurane and an intraoperative infusion of dexmedetomidine with a concentration of 10 μg·kg−1·h−1. Group C served as the control group and received no treatment. Group D received an inhalation dose of 2% sevoflurane. Results: In relation to the model establishment, we found that there was no significant difference in body weight and swimming speed before and after modeling. There was no statistically significant difference in the escape latency between Groups A, B, C, and D before modeling. After modeling, there was no statistical difference in the escape latency between Groups A, B, and C, but the difference was statistically significant when compared to Group D (P<0.05). In relation to the dexmedetomidine intervention, we found that compared to Group C, MWM test performance in Group A and B was considerably worse (longer escape latencies and fewer platform crossings within 90 seconds), and were more significant in Group A. .Compared with Group D, the levels of IL-1, IL-6, and TNF-α of the brain homogenates were elevated, and this elevation was highest in Group A, followed by Group B; The pathological changes were consistent with changes in behavioral tests. In group A, there were obvious disorders of glial cell arrangement, apoptosis and deletion. There was no significant change in group D. And the changes of vertebral cells in group B and group C were slight, with orderly arrangement and intact cell structure.Conclusions: Dexmedetomidine inhibits the apoptosis of hippocampal cells and reduces the cognitive dysfunction of rats with MCI induced by D-galactose via the inhibition of the release of inflammatory cytokines.

Abstract Background The objective of this study was to assess the inhibitory effect of intravenous injection of butorphanol on the shivering in those parturients who underwent cesarean section (CS) under epidural anesthesia (EA). Methods 160 parturients planned for elective CS under EA were enrolled and finally 155 of them were included in this trial and randomly allocated to 4 groups. Before epidural anesthesia, parturients in Group A, B and C were respectively injected 7.5μg/kg, 5μg/kg and 2.5μg/kg butorphanol (100ug/ml) while none in Group D was given any drug. The incidence, duration and intensity of shivering, hemodynamic parameters of parturients, Apgar score of neonates, analysis of blood gas of umbilical cord and adverse events were recorded. Results The demographic characteristics of parturients of the four groups were similar. Compared with the control group (Group D), statistically significant attenuation of shivering was seen in the parturients of Group A and Group B. The incidence, intensity and duration of shivering of the Group A and Group B were all lower than those of the control group, but there was no statistical difference in the incidence, severity or duration time of shivering among groups receiving butorphanol. No patient displayed grade 4 shivering. There were no significant differences among the groups with mean arterial pressure (MAP), heart rate (HR), pulse oxygen saturation (SpO2), respiratory rate (RR) after administration of butorphanol. The incidences of most adverse effects such as nausea and vomiting, respiratory depression, and hypotension were also not seen statistical difference among the four groups. However, compared with other three groups, sedation parameter increased in Group A. Compared with Groups C and Group D, incidences of dizziness increased in Group A and Group B. There was no significant difference in Apgar score, PH, PCO2, PO2, HCO3- and lactic acid value among the newborns of the four groups. Conclusion The prophylactic administration of intravenous butorphanol 0.75μg/kg or 0.5μg/kg is effective on inhibiting shivering and can be safely used in parturients undergoing CS under EA, but 0.5μg/kg is more suitable because of less sedation. Dizziness of parturients should be monitored whichever dose is used.

Objective Exposure of dichlorvos-contaminated foods, water and environment can lead to decrease in proper liver function. Thus, Mimosa pudica(MP)is being investigated in the present study to determine its protective effect on dichlorvos induced hepatotoxity in Mice. Methods Fifty adult male BALB/c mice weighing between 20-30g were randomly assigned into 5 groups of 10 animals each (Groups A, B, C, D, and E). Group A as the control Group received normal feed, group B received 0.1 ml of MP, group C was given 40 g of 2.5% Dichlorvos (DDVP) for 28 days. While, group D were given 40 g of 2.5% DDVP with 0.1ml of MP and group E animals were given DDVP for half the period of administration, normal feed and 0.1ml MP for 14 days. Histological and biochemical preparations of the liver were processed and data were expressed as mean± SEM. Significant difference was set at p<0.05. Results ALT activity and the total protein level of the liver show no significant increase (P < 0.005) when compared with the control. AST and ALP activities were significantly increased in animals given DDVP with subsequent MP treatment when compared with the controls. Histological studies revealed distortion of normal hepatic histoarchitecture in DDVP group B and MP groups mitigated these changes in the treated groups. Conclusion Dichlorvos caused tissue distortion in the mice with prominent toxic effects on the liver while MP extract showed ameliorative effects on the liver that was exposed to DDVP

Background: Nerve connectors are short nerve conduits used to approximate nerve ends. Acellular nerve allografts are viable alternatives when direct repair is not possible but do not produce exudate essential for fibrin clot formation. We hypothesize that acellular nerve allograft implanted using nerve connectors must have end-to-end contact with the in situ nerve stumps to support nerve regeneration. Methods: Sixty Sprague Dawley rats underwent a 14-mm unilateral tibial nerve injury and subsequent repair using various combinations of acellular nerve grafts and nerve connectors. Proximal repairs for all groups utilized direct contact with the nerve stump within connector. Variations in distal repair methods (allograft length, nerve gap, and connector length) defined our 4 groups—group A: 14 mm allograft, no distal gap, and distal connector; group B: 11.5 mm allograft, 2.5 mm distal gap, and distal connector; group C: 9 mm allograft, 5 mm distal gap, and distal connector; group D: 14 mm allograft, no distal gap, and no distal connector. At 3 months post-repair, function and histomorphology were assessed. Results: Developed muscle force was significantly lower in group C (0.073 ± 0.077 N) compared with the other 3 groups (group A = 0.529 ± 0.312 N, group B = 0.461 ± 0.462 N, and group D = 0.409 ± 0.327 N). Axon counts were significantly lower in group C (2121 ± 389) compared with group A (6401 ± 855), group B (4710 ± 755), and group D (4450 ± 126). There was no statistically significant difference in G-ratios (myelination) between groups ( P > .05). Conclusion: Nerve regeneration was significantly impaired as the gap distance between the distal end of the allograft and the distal nerve stump increased to 5 mm.

Objectives: To observe the effect of lagenaria siceraria on inflammation and fibrosis brought about by arsenic in liver of Sprague Dawley rat. Study Design: Laboratory based randomized control trial. Place and Duration of Study: This experiment was performed at Department of Anatomy, Army Medical College Rawalpindi in co-operation with National Institute of Health (NIH) Islamabad for eight weeks (1st March 2017 to 25th April 2017). Material and Methods: Fifty Sprague Dawley rats (both male and females housed separately) were carefully chosen and distributed randomly into five groups, each consisting of 10 animals. A and B were the control groups whereas C, D and E served as experimental groups. During the first four weeks, experiment groups C, D and E were given a dosage of 5milligram/kilogram body weight of sodium arsenite. At the end of four weeks, animals from control group A and experimental group C were dissected and liver samples were processed for microscopic studies. In the next 4 weeks, group D animals were set aside without any further intervention. At that time, sodium arsenite at a dose of 5 milligram/kilogram body weight and lagenaria siceraria at a dose of 100 milligram/kilogram bodyweight were administered to group E animals. Group B animals served as control for experimental groups D and E. At the end of these 4 weeks animals of groups B, D and E were dissected. Liver was processed, fixed and stained for microscopic study. Area of portal triad as well as liver lobules were studied for inflammation and fibrosis and results were analysed. Statistical tool used to analyse the data was SPSS v 22. Results were considered to be significant when p-value is ≤ 0.05. Results: Experimental group C developed moderate grade fibrosis and inflammation (grade 2 to 3) as compared to group A. Degree of inflammation and fibrosis was mild to moderate (grade 1 to 2) in group D. There was no inflammation and fibrosis (Grade 0 to 1) in group E. Group B served as a control for group D and E. Conclusion: Inflammation and fibrosis developed in the liver of adult rats when they were subjected to sodium arsenite even for a brief calculated period. Simultaneous administration of lagenaria siceraria can shield and diminish the toxic effects of arsenic. Oxidative potential and immunomodulatory properties and presence of flavonoid like substances renders lagenaria siceraria to act as ameliorative against this fibrosis and inflammation in liver lobules and surrounding area of portal triads.

The aim of this study was to evaluate the effect of buserelin injection on day 12 postinsemination on fertility in lactating dairy cattle. A total of 57 cows were assigned to two groups and four subgroups. In the treatment group, the cows were synchronized with PGF2α-PGF2α (group A) or GnRH-PGF2α (group B) protocol, and buserelin was injected on day 12 postinsemination. Cows in the control group were synchronized with PGF2α-PGF2α (group C) or GnRH-PGF2α (group D) protocol, saline solution was injected on day 12, and served as controls. Pregnancy rates on day 21 and 45 and embryonic death rates were 85.7%, 71.4% and 16.7%, 85.7%, 85.7% and 0.0%, 73.3%, 62.1% and 27.3% and 85.7%, 71.4% and 16.7% in groups A, B, C and D, respectively. There was no significant difference between synchronization protocols for pregnancy rates, and among groups A, B, C and D for pregnancy rates and embryonic death rates. Mean progesterone concentrations in pregnant cows in groups A and B were higher than that in groups C and D, respectively, on day 18 and 21 (p < 0.05). In conclusion, GnRH injection on day 12 postinsemination increased the plasma progesterone concentrations on day 18 and 21 postinsemination. However, it did not alter the pregnancy rates and prevent embryonic deaths.

In recent times the use of high fat ketogenic diet as a treatment strategy in some diseases and weight control has been on the increase. This study aims to elucidate the effect of high fat ketogenic diet on some renal and liver parameters. Forty albino rats were used and divided into four groups. Group A was control; B, C, and D were fed with diets including butter, coconut oil and olive oil respectively for eight weeks. Urine and serum samples were assayed spectrophotometrically. There was a significant difference in urinary albumin (0.13&plusmn;0.01g/dl) of group D when compared with control (0.22 &plusmn; 0.03g/dl). Urinary creatinine concentrations of group D (4.32&plusmn;0.70mg/dl) was higher than group C (1.75&plusmn;0.46 mg/dl). Urea of group B (39.40&plusmn;4.70 mg/dl), group C (29.90&plusmn;1.46 mg/dl) and group D (40.20&plusmn;2.62mg/dl) were lower than control group (64.20&plusmn;3.41mg/dl). Serum creatinine concentrations of group B (1.05&plusmn;0.09mg/dl), group C (0.85&plusmn;0.07lmg/dl) and group D (1.03&plusmn;0.07 mg/dl) were reduced significantly. Albumin: creatinine ratio of group A (120.6&plusmn;32.04) was higher than that of group D (41.31&plusmn;8.28). AST (260.1&plusmn;17.80) was higher in group C compared with A (160.1&plusmn; 9.510). ALT for D (91.20&plusmn;18.70), group A (36.00&plusmn;3.84), serum albumin concentrations of group D (3.590&plusmn;0.1286), group C (3.590&plusmn;0.1286) and group A (4.100&plusmn;0.1814). Total protein concentration of group C (5.390&plusmn;0.2105), D (5.280&plusmn; 0.1104) and group A (6.190&plusmn;0.2496g). Body weight of experimental groups reduced while the control groups increased. This study has confirmed that high fat ketogenic diet can be used for weight management however it could be harmful to the liver but did not show any harmful effects on the kidneys.

The quest for excellence in mental and physical health is not new. We find various references and formulations in Ayurvedic classics meant for promoting mental and physical health of a child. Suvarna Prashan is one of the formulations explained in age old Ayurvedic classic Kashyap Samhita. This formulation is very widely used now days as a memory and immune booster for children. But there is very little systematic documented study which can be used to evaluate the efficacy of the formulation. Suvarna Bhasma was prepared in Ayurved Rasayani Pharmacy, Pune. Madhu and Ghrita were collected from KLE Ayurveda Pharmacy, Belgaum. Suvarna Bindu Prashan was prepared in KLE Ayurved pharmacy, Belgaum. It contains Suvarna Bhasma, Ghrita and Madhu. Twenty apparently healthy male and female children with age group of three to four years were ready to sign inform consent form were selected into two groups each. Subjects in Group A received Suvarna Bindu Prashan where as Group B (Control group) did not receive any treatment. Both the groups were observed for six months. Children in Suvarna Bindu Prashan group showed significant reduction in the scores of eating habits, behavior, mood, temperament and scores of event of illness. However there was no significant difference in the score of sleeping habit. There was significant increase in IQ percentage.

<b><i>Introduction:</i></b> The aim of this was to describe the predictors of mortality related to COVID-19 infection and to evaluate the association between overweight, obesity, and clinical outcomes of COVID-19. <b><i>Methods:</i></b> We included the patients &#x3e;18 years of age, with at least one positive SARS-CoV-2 reverse transcriptase-polymerase chain reaction. Patients were grouped according to body mass index values as normal weight &#x3c;25 kg/m<sup>2</sup> (Group A), overweight from 25 to &#x3c;30 kg/m<sup>2</sup> (Group B), Class I obesity 30 to &#x3c;35 kg/m<sup>2</sup> (Group C), and ≥35 kg/m<sup>2</sup> (Group D). Mortality, clinical outcomes, laboratory parameters, and comorbidities were compared among 4 groups. <b><i>Results:</i></b> There was no significant difference among study groups in terms of mortality. Noninvasive mechanical ventilation requirement was higher in group B and D than group A, while it was higher in Group D than Group C (Group B vs. Group A [<i>p</i> = 0.017], Group D vs. Group A [<i>p</i> = 0.001], and Group D vs. Group C [<i>p</i> = 0.016]). Lung involvement was less common in Group A, and presence of hypoxia was more common in Group D (Group B vs. Group A [<i>p</i> = 0.025], Group D vs. Group A [<i>p</i> &#x3c; 0.001], Group D vs. Group B [<i>p</i> = 0.006], and Group D vs. Group C [<i>p</i> = 0.014]). The hospitalization rate was lower in Group A than in the other groups; in addition, patients in Group D have the highest rate of hospitalization (Group B vs. Group A [<i>p</i> &#x3c; 0.001], Group C vs. Group A [<i>p</i> &#x3c; 0.001], Group D vs. Group A [<i>p</i> &#x3c; 0.001], Group D vs. Group B [<i>p</i> &#x3c; 0.001], and Group D vs. Group C [<i>p</i> = 0.010]). <b><i>Conclusion:</i></b> COVID-19 patients with overweight and obesity presented with more severe clinical findings. Health-care providers should take into account that people living with overweight and obesity are at higher risk for COVID-19 and its complications.
