Biological Tests

Diabetic animals induced by alloxan show severe hyperglycemia and intense catabolism characterized by the absence of insulin. Therefore, the objective of this study is to assess whether the alloxan 6CH, is able to reverse or mitigate the changes promoted by diabetes mellitus, as well as assess the effects of thymulin. In biological tests male Wistar rats were used induced to experimental diabetes by the administration of alloxan (iv 42 mg / kg). The sample comprised four groups (n = 4): G1 – control without the induction of diabetes, G2 - diabetic without treatment, G3 - diabetic treated with thymulin 12CH and G4 - treated with alloxan 6CH. The data were statistically analyzed by ANOVA followed by Tukey-Kramer test (p < 0.05). After treatment for 40 days slight decrease of glucose in animals treated with alloxan (502 ± 28) mg/dl and thymulin (500 ± 10) mg/dl was observed compared with untreated animals (563 ± 23)mg/dl. Remained unchanged feed intake and water, however, significant decrease of body weight in diabetic group (96 ± 21)g was observed compared to animals treated with alloxan (27 ± 23)g and thymulin (20 ± 16)g, fact not observed when the last two groups are compared with the control (5.1 ± 3.9)g. Significant reduction in the percentage of lymphocytes in diabetic animals (44.8 ± 2.4)% and increase in the group treated with thymulin (12CH) (83.3 ± 4.5)% was checked, when compared to the others. Animals treated with alloxan and thymulin showed clinical improvement. Based on these findings it is concluded that alloxan and thymulin improve the general state of the animal, and suggest inhibition of strong catabolism observed in diabetic animals without treatment.

Streptozotocin Induced Diabetes

Study was conducted to evaluate the hepatoprotective effects of Seabuckthorn leaf extract (SLE) supplementation on serum enzymatic levels in streptozotocin (STZ) induced diabetes mellitus in Wistar rats. Thirty-two adult male Wistar rats were divided into four groups namely CON (negative control), SCO (Seabuckthorn control), DCO (Diabetic control), and DSL (Diabetic seabuckthorn treatment group). Diabetes mellitus was induced by single intra peritoneal injection of STZ @ 50 mg/kg body weight in DCO and DSL group of rats. SLE was administered orally @ 100mg/kg body weight for 40 days to SCO and DSL groups. CON served as the negative control. Blood samples were collected from experimental animals on zero, 20th, and 40th days of trial to study liver specific serum enzyme profile viz aspartate amino transaminase (AST), alanine amino transaminase (ALT), alkaline phosphatase (ALP) and acid phosphatase (ACP). Significantly (P less than 0.01) higher levels of all the enzymes studied were observed in experimentally induced diabetic rats in comparison to normal rats. However, in SLE treated diabetic rats (DSL group), significant (P less than 0.01) improvement was observed in all the above enzymes. It may be concluded that SLE exerts hepatoprotective effect in STZ induce Diabetes mellitus in Wistar rats.

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.

Background: Traumatic ulcers in patients with diabetes mellitus may experience delayed healing despite their diabetic condition being controlled. Liquid smoke coconut shell containing phenolic compounds can potentially accelerate the healing process. One healing process indicator is the increased number of fibroblasts, another being the increased amount of collagen. Purpose: This study aimed to analyze the amount of collagen in traumatic ulcers in diabetics after application of liquid smoke coconut shell. Methods: Alloxan was induced in twenty-four male Wistar rats as models of diabetes mellitus. A traumatic 10 mm ulcer was made along the labial fornix incisive inferior with a round, stainless steel blade before liquid smoke coconut shell and benzydamine hydrochloride (as the control) was administrated once a day. A biopsy of the labial fornix incisive inferior was subsequently performed after the topical application for 5 and 7 days. Histological assessment was conducted to analyze the amount of collagen by means of Masson Trichome staining. Results: Histologically, the topical application of liquid smoke coconut shell for 5 days significantly increased the amount of collagen, higher than that of benzydamine hydrochloride as the control (p=0.006) (p<0.05). Meanwhile, the topical application of liquid smoke coconut shell for 7 days made the concentration of collagen no significantly different from that of benzydamine hydrochloride as the control (p=0.156) (p>0.05). Conclusion: Liquid smoke coconut shell applied for 5 days increase the amount of collagen in traumatic ulcers in diabetic patients.

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.

Observation Period

AbstractThe experiment was conducted on 10 Wistar rats, male and female, with initial body weight 270–280 g (males) and 250–260 g (females). The drug was administered using a spray cap in 10 doses of 0.1 mg at 45 min intervals. The average cumulative dose of the drug per naloxone hydrochloride was 36.6 mg/kg for males and 39.4 mg/kg for females. The animals were monitored for 2 weeks after the exposure and then euthanized by a gentle decapitation.We noticed that after each drug administration the animals showed a decrease in motor activity. During the observation period there were no animal deaths or signs of abnormalities in their general state or behavior. Beginning on day 7 a significant increase in body weight of the animals was noted in comparison with the initial data. The relative mass of the internal organs of the treated rats remained within the physiological norm.We conclude that naloxone hydrochloride after an intranasal administration at 36.6 mg/kg for males and 39.4 mg/kg for females does not cause death of animals and or have a toxic effect on their general state, does not change their protein metabolism characteristics or the appearance of the internal organs and their mass.

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.
