Evaluation of liver and renal functions are routine tests performed in preclinical studies. Liver plays a role in detoxification and secretion of various substances to regulate a wide range of metabolic functions. Kidneys serves as the main excretory and osmoregulatory organs. Thus, assessment of liver and renal functions are important in identifying the presence of damages and diseases as well as monitoring body responses towards treatments or therapy. Therefore, normal values should be established for valid reference. Until now, many researchers still use references from various publications, including foreign countries with different environmental factors and method of animals care. This study was aimed to provide reference values for liver and renal functions in male and female Wistar rats. Animals were sourced from LPPT-UGM. Age 4-, 6-, and 8-week-old represent juvenile, preadult, and adult. Blood samples were collected from orbital sinus of anesthetized animals. Sera were tested for ALT, AST, BUN, and creatinine based on spectrophotometry. Results demonstrated that values of most parameters varied, depend on sex and age. According to this finding, it can be concluded that reference values cannot be generalized but must be determined by sex and age in local population.

Leptin is an adipose-derived hormone with established roles in energy balance that can impact the response to refeeding after malnutrition. Although the amount of circulating leptin has traditionally been associated with the amount of adipose tissue, controversy exists as to whether this relationship is constant in both humans and animals and over a wide range of body composition. Our objective was to evaluate whether the leptin – body fat ratio is constant in the range of healthy to low body mass in female Wistar rats. Eight ad libitum fed (C) and eight food-restricted (FR) rats were compared over a period of four weeks. FR rats attained the target 75% of baseline body mass after the first two weeks, which was maintained for the remaining two weeks. Serum leptin and IGF-1 (ELISA) and body composition (DXA) were measured at baseline (t0) and once weekly for the remainder of the study (t1–t4). The leptin – body fat ratio was reduced during the two-week period of weight loss (t0 = 0.036 ± 0.016 (ng·mL–1)·g–1 vs. t1 = 0.010 ± 0.004 (ng·mL–1)·g–1 and t2 = 0.015 ± 0.007 (ng·mL–1)·g–1, p < 0.05). Leptin concentration plateaued at its nadir (~0.24 (ng·mL–1)·g–1) at fat mass < 22 g. IGF-1 was correlated with lean mass (r = 0.45, p < 0.05) and fat mass (r = 0.58, p < 0.05), regardless of body mass. We concluded that the leptin – body fat ratio was reduced early in food restriction and the correlation between these two variables was absent at low body fat.

This research aimed to examine the time of onset and sedation on diabetic mellitus (DM) rat (Rattus norvegicus) by propofol. This study used 8 female wistar rats 2-3 months old and 150-200 grams of bodyweight, fed with standard feed and water ad libitum. Samples were divided into two groups. Group 1 (KI) as a control group was injected intraperitoneally with aloxan solvent and group 2 (KII) was injected intraperitoneally with 150 mg/kg bodyweight aloxan. Blood glucose was checked 10 days after aloxan injection, DM was categorized if the blood glucose over 150 mg/dl. All rats were injected intravenously with propofol 1% with the dose of 10 mg/kg bodyweight. Onset and sedation time was counted using stopwatch after propofol injection. The result showed that mean (±SD) of onset on KI and KII were 1.39±0.49 and 8.64±1.23 seconds, consecutively and they were significantly different at P0.01. Whilst mean (±SD) of sedation KI and KII were 12.12±1.47 minutes and 7.62±1.61 minutes, respectively. The onset and sedation time of KI was significantly different from KII P0.01. The conclusion of this research was DM affects time of onset and sedation when wistar strain rats were anesthetized by 1% propofol.Key words: rats, diabetic mellitus, propofol, onset, sedation

Biochemical Assessment

The biochemical assessment in animals is of capital interest to define the diagnosis of many diseases. The variation of biochemical parameters (urea, glycemia, creatinemia, transaminases: GPT and GOT, total cholesterol, HDL-c, LDL-c, triglycerides and total lipids) is an indicator of the state of health of certain vital organs such as the kidney, liver, pancreas, veins, heart, etc... . For this study, to be able to determine the normal values of the rats, a set of batches of male and female Wistar rats was formed and acclimatized for 2 months. Each batch set consisted of thirty-nine (39) rats. Each rat was weighed and then sampled by venipuncture at the caudal level to collect their blood in a dry tube (red). The red tube was used to determine the biochemical parameters. The results of this study showed that some animals already had certain pathologies before the use of any beneficial or harmful substance on them. However, most of the animals used have normal biochemical parameters revealing the good state of their various vital functions (kidney, liver, heart, veins, pancreas, etc.). These values of determining standard biochemical parameters can form a basis for future tests.

ABSTRACT The mechanisms involved in the prolongation of the oestrous cycle following LH administration were studied in 4-day cyclic female Wistar rats. In females injected with LH on the morning of dioestrus I there was an increase in ovarian venous blood progesterone as compared with non-injected animals. In both LH-treated females, and those injected with progesterone on the morning of dioestrus I, a slowing up in follicular growth was observed from the afternoon of dioestrus I. The size of follicles greater than 400 urn present in LH or progesterone injected animals on the third day of cycle was similar to the size reached by the same range of follicles in non-injected animals on the second day of the cycle. Hence, the increase in endogenous ovarian progesterone elicited by LH was considered as the cause of the slowing up of follicular growth and therefore of the lengthening of the oestrous cycle duration in female rats injected with LH at the beginning of 4-day cycle.

Wound examination is indispensable in forensic practice. The scientific field of wound age determination has advanced progressively during recent years.The purpose of this study was to determine the differences of fibronectin and TGF-β1 expression in both antemortem and postmortem wounds. This study was an experimental with completely randomized design.  The skin wounds (vital and postmortem) were taken from fourty Wistar rats and divided into 10 groups of rats. Immunohistochemical staining was performed to determine the differences between antemortem and postmortem wounds. The result showed that in 30 minutes after antemortem wound infliction, all of samples showed weak reactivity for fibronectin and TGF-β1 (100%).  In first hour after wound infliction, 3 samples (75%) showed weakly positive and 1 sample (25%) strongly positive for fibronectin and TGF-β1.  In 2 hour after wound infliction, 1 sample (25%) showed weakly positive and 3 sample (75%) strongly positive for fibronectin and TGF-β1.  In 3 and 4 hour after wound infliction, all of samples strongly positive for fibronectin and TGF-β1.  In postmortem wound, all of samples showed negativity for fibronectin and TGF-β1. In conclusion, fibronectin and TGF-β1 may be useful in the determination of wound vitality. Keywords: wound, fibronectin, TGF-β1, vitality
