Cydonia oblongaMiller (quince) is regarded as a potent libido invigorator in Tib-e-Nabvi and Unani System of Medicine. This study was carried out to evaluate the aphrodisiac activity of the hydroalcoholic extract of the fruits ofCydonia oblongaMiller (quince) in Wistar rats. The extract was administered orally by gavage in the dose of 500 mg/kg and 800 mg/kg body weight per day as a single dose for 28 days. The observed parameters were mounting frequency, assessment of mating performance, and orientation activities towards females, towards the environment, and towards self. The results showed that after administration of the extract mounting frequency and the mating performance of the rats increased highly significantlyP<0.01. The extract also influenced the behaviour of treated animals in comparison to nontreated rats in a remarkable manner, making them more attracted to females. These effects were observed in sexually active male Wistar rats.

Aims: To study the protective effect of hydroalcoholic bark extract of Terminalia arjuna against DBTC induced pancreatic cancer in male wistar rats. Study design: Healthy male Wistar Albino rats weighing 150-200 g were segregated into four groups (n=6). Group I was considered as normal control, received normal saline (0.9%w/v, 1 ml/kg body weight, orally). Group II rats were treated with DBTC (6 mg/kg body weight, i.p.) which served as negative control. Group III and IV received Terminalia arjuna Linn bark hydroalcoholic extract at doses of 250 mg/kg body weight, per oral and 500 mg/kg body weight, per oral respectively. Place and Duration of Study: University College of Pharmaceutical Sciences, Andhra University, Visakhapatnam, Andhra Pradesh, India, between May 2020 and July 2020. Methodology: The experimental animals were segregated into four groups of six rats each. According to acute toxicity data, 250 mg/kg as low dose and 500 mg/kg as high dose of the test compound have been chosen for administration. All the drugs were given for 28 consecutive days to all the respective groups with standard pellet diet and water ad libitum. The assessment of serum parameters such as α-Amylase, Lipase and blood glucose levels were carried out on 1st day, 14th day and 28th day to the respective groups. Results: Pretreated groups of Terminalia arjuna Linn bark hydroalcoholic extract (250 mg/kg and 500 mg/kg body weight, orally) showed significant (‘#’p<0.001) decrease in the levels of α-Amylase, Lipase and glucose in the blood when compared to DBTC (6 mg/kg body weight, i.p.) induced group which served as negative control. Conclusion: This study suggests that Terminalia arjuna may have a protective role against DBTC induced pancreatic cancer in male wistar rats and further investigation may be required to confirm its therapeutic potentials clinically.

Objective: The study evaluated the hypolipidemic and anti-inflammatory potential of the hydroalcoholic extract of P. Aculeata (HEPa/EtOAC) in Wistar rats fed with Westernized diet. Methods: The experiment was approved by the Ethics Committee (Federal University of Pernambuco-23076.027165 / 2010-21). The hydroalcoholic extract (HEPa/EtOAc) was obtained from the aerial parts of P. Aculeata and portioned by acetate/ethanol in different concentrations. 36 male Wistar rats were initially divided into two groups: Control (C, n = 6), fed a commercial diet (26g / 100g of protein; 63g / 100g of carbohydrates; 11g / 100g of lipids) and Westernized (W; n = 30) – fed an experimental diet (15g / 100g of protein; 51g / 100g of carbohydrates; 34 g/100g of lipids) receving water ad libitum. After 4 months of diet, W group was arbitrarily redistributed into six subgroups according to water supplementation, or different extracts concentrations: (n = 6 animals/group): W- distilled water (1mL/kg; po); WG – genfibrozil (140 mg/kg; p.o.); W35- 35 mg/kg; W70 – 70 mg /kg; p.o. and W140- 140 mg/kg; p.o for 30 days. The lipid profile and pro-inflammatory cytokines were analyzed. Results: The westernized diet caused dyslipidemia and the treatment with HEPa-EtOAc (140mg / kg), promoted a significant reduction in the concentration of pro-inflammatory cytokines, in total cholesterol, in the LDLc and serum triglycerides. Conclusion: The reduction of dyslipidemia and pro-inflammatory cytokines from the of P. Aculeata extract corroborate the ethnopharmacological potential of the plant, already used by the population for hypoglycemic purposes.

The metabolic response to nutrient ingestion and the rate of digestion and absorption of nutrient molecules in bowel physiology plays an important role in the metabolic control of some human chronic non-infectious diseases. This experimentally-controlled designed nutritional study which lasted eight weeks aimed to determine the effects of proportional high-protein/low-carbohydrate (HP/LC) formulated diet on glycemic tolerance, glycemic control, body weight, organ weight and organ morphometry in healthy and diabetic adult male Wistar rats. Twenty-four male Wistar rats purchased from a disease-free stock were randomly categorized into four groups (n = 6, each) after two weeks acclimatization period in raised stainless steel cages with 6 mm2mesh floor and replaceable numbered blotters papers placed under each cage in a well-ventilated animal house. Animal groups include: Healthy control group (HC), Healthy treated group (HT), Diabetic control group (DC) and Diabetic treated group (DT. The animals were fed according to the experimental design with water ad libitumfor eight weeks. Diabetes was inducted with freshly prepared alloxan monohydrate solution (150 mg/kg bw, intraperitoneally). Body weights and fasting blood sugar concentrations were measured twice weekly, while oral glucose tolerance test was conducted on the last day of the eighth-week study and subsequently followed by organs extraction after anesthesia for weight and gross assessment. Proportional high-protein/low-carbohydrate formulated diet caused significant reduction in mean body weight of treated diabetic (DT: 22.6%; P= .001) and healthy (HT: 5.8%; P= .007) rats while the control animals on control diet recorded significant (P< .05) increase in body weight gain (DC: 12.4%; HC: 11.2%). Glycemic tolerance and control improved significantly in diabetic treated rats over that of the healthy treated rats. Gross morphometry of the extracted organs (kidneys, liver, heart, lungs, spleen and testes) revealed sustained normal morphological features without any visible lesion. In conclusion, consumption of proportional high-protein/low-carbohydrate formulated diet enhanced body weight reduction and sustained normal organ morphological features with good glycemic tolerance and control in experimental rats, suggesting its dietary potentiality, safety and suitability to ameliorate obesity-related diabetes.

The effects of a hypothalamic paraventricular nucleus (PVN) lesion on energy balance were investigated in exercise-trained rats. Male Wistar rats weighing initially 250 g were divided into four groups. Two groups of rats underwent a bilateral PVN lesion, whereas the two remaining groups were sham operated. The PVN lesions were done electrolytically. One group from each surgical treatment was exercised, while the other group was kept in sedentary conditions. Rats were exercised on a rodent motor-driven treadmill at moderate intensity, 1 h/day for 21 consecutive days. Food intake and body weight were measured each day during the study. At the end of the treatment period, rats were killed, and carcasses were analyzed for their energy content. Serum corticosterone was measured by a competitive protein-binding assay. Energy gain and energy intake were lower in exercised rats than in sedentary controls, regardless of whether they were sham or PVN lesioned. Concurrently, there was no difference in the energy gain between PVN-lesioned and sham-operated rats, despite the fact that PVN-lesioned rats ended the experiment with a larger body weight than the sham-lesioned animals. Serum corticosterone levels were lower in PVN-lesioned rats than in sham-lesioned rats. In conclusion, the present results indicate that the PVN, the hypothalamic nucleus predominantly controlling the pituitary-adrenal axis activity, is not a prominent structure in the regulation of energy balance in exercised male Wistar rats.

We analyzed retrospectively data from 148 chow-fed male Wistar rats killed between the age of 6 wk and 2 yr while varying in body weight from 136 to 917 g. The purpose of this study was to clarify the relationship of body weight and body lipid content with the composition and cellularity of the epididymal and retroperitoneal fat depots. A positive linear association was found between body weight and body water or fat-free dry residue, whereas total body lipid exhibited a curvilinear relationship with body weight. The weight of the epididymal pads was linearly related to body weight but not to body lipid. In contrast, retroperitoneal pad weight was exponentially related to body weight and paralleled total body lipid. A strong linear correlation was found between total body lipid and weight (r = 0.959) or depot lipid content (r = 0.967) of the retroperitoneal fat pads. In this rat model of aging and spontaneous obesity, significant regional differences exist in adipose depot composition and cellularity. A practical outcome of this study is a simple and accurate prediction of body lipid content from the gravimetric determination of the retroperitoneal fat depots.

The toxicological effect of the aqueous extract of fresh, dried and boiled berries of Solanum aculeastrum Dunal at 1, 10 and 25 mg/kg body weight was investigated in male Wistar rats for 28 days. The parameters used were the body weight of the animals and absolute weights of the organs, haematological parameters, renal and liver functional endpoints. The animals gained appreciable weight and showed no signs of clinical toxicity. The dried (DB), boiled dried (BDB), fresh (FB) and boiled fresh berry (BFB) extracts reduced (p < .05) the heart-, liver-and spleen-body weight ratio of the animals whereas that of the lung was not altered. The kidney and testes-body weight ratios were specifically altered by the different extract. All these were not accompanied by any histomorphological changes. The extracts did not alter (p > .05) the levels of RBC, Hb, PCV and albumin of the animals. The platelets were decreased by the DB and FB whereas BFB increased this parameter. The FB and BFB at all the doses also reduced the mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) of the animals. With the exception of the FB where the creatinine and chloride levels decreased, other extracts did not alter the level of these kidney parameters. Only FB increased the levels of uric acid and urea. All the extract decreased the serum alanine aminotransferase (ALT) of the animal. The levels of total protein, globulin, total and conjugated bilirubin were not altered by DB and BDB whereas these indices were increased by FB and BFB. The DB and BDB increased the serum alkaline phosphatase (ALP) activity whereas FB decreased the activity of the enzyme. In contrast, DB and BDB decreased the serum aspartate aminotransferase (AST) activity of the animals whereas FB and BFB increased the activity of the enzyme. The FB and BFB also increased the levels of potassium, magnesium and phosphorus of the animals. Overall, the alterations in the biochemical parameters by the various extracts of S. aculeastrum berries at these doses indicated that the normal functioning of these organs may be adversely affected. However, drying and boiling might reduce the toxic effect of the berries.

Abstract Fasting and thyroid hormone have been reported to modulate the β-adrenergic pathway of lipolysis in rat, but their effects on the α2-adrenergic response are not well known. The purpose of the present study was to investigate this point. Male Wistar rats, 3 weeks old, were thyroidectomized surgically, kept for 1 month at 25 °C and then fasted or not fasted for 3 days with or without daily intraperitoneal injection of 3,5,3′-tri-iodo-l-thyroni(T3; 4·6 nmol/100 g body weight). Age-matched, sham-operated, fed and fasted euthyroid rats were used as controls. The experiments were carried out using isolated epididymal adipocytes. The α2-adrenergic agonist UK 14304 (UK) inhibited the stimulated lipolysis more in fed than in fasted euthyroid rats whereas it had no effect in hypothyroid or T3-treated hypothyroid rats. The α2-adrenergic antagonist idazoxan reversed the antilipolytic effect of UK more in fasted than in fed euthyroid rats. The α2-adrenergic antagonist RX 82 1002 (RX) did so, but at lower concentrations than those of idazoxan. Idazoxan slightly increased the glycerol release in hypothyroid and especialiy T3-treated hypothyroid rats. RX had practically no effect on the production of glycerol in these animals. The findings suggest that (a) fasting and probably hypothyroidism decrease the α2-adrenergic response in adipocytes from rats, (b) T3 treatment of hypothyroid rats has no effect on the α2 response, and (c) thyroid hormone does not directly modulate the α2-adrenergic response in rat adipocytes.
