Xanthophylls, such as lutein and zeaxanthin, have received increasing interest in recent years because of positive correlations between their consumption and the prevention of eye diseases. Numerous human intervention studies have been conducted with lutein to estimate the bioavailability from different formulations. The present study was designed to obtain basic data on the absorbance efficiency of the monohydroxylated counterparts of lutein and zeaxanthin: α- and β-cryptoxanthin. A corn-oil-based diet comprising ß-cryptoxanthin from papaya purée and α-cryptoxanthin from green carrot leaves was fed to five female Wistar rats for 8 consecutive days at a rate of 17·3 nmol/d and 9·2 nmol/d, respectively. The identity of the xanthophylls in the supplement was ascertained by LC-(APCI)MS analyses, and xanthophylls present in liver and plasma samples were determined by HPLC/diode array detector (DAD). The β-cryptoxanthin concentrations of rat livers in the treatment group were statistically distinguishable (P < 0·01) from those present in the livers of the control group that were fed a basic diet. α-Cryptoxanthin, the second xanthophyll present in the supplement, was not found in rat livers in the treatment group. Plasma samples were free of xanthophylls. This is the first report proving that β-cryptoxanthin has a higher absorption efficiency than α-cryptoxanthin in rats, at least from a minimally processed oil-based xanthophyll supplement.

This study aims to look at the histopathological picture of the dorsal arteries of the penis of the hiperlipidemic wistar rats (Rattus novergicus) induction by high-fat diet that seen in terms of lumen diameter and thickness of the arterial endotelium wall. Hyperlipidemia is a risk factor for ateriosclerosis in the penile arteries causing erectile dysfunction in men. This study is an experimental study with a randomized posttest only control goup design. The sample are  10 individuals adult male wistar rats aged 3-4 months with a range of body weight 150-200 grams. Before treatment, adaptation was carried out for 7 days. After that the sample rats in the treatment group were made hyperlidemic by feeding lard for 50 days. Then surgery is performed for histopathological preparations at the posttest. To determine the differences in endotelium thickness and arterial lumen diameter in the two groups, an independent t-test was used. Thick diameter data of the endotelium and dorsal arteries of the penis of the wistar rat between the lower treatment group and the control group. The difference that occurred was statistically significant (p <0.05). So it can be concluded that the provision of high-fat diet (hyperlipidemia) decreases the lumen diameter and endotelium thickness of dorsal arteries penis.

Abstract The prenatal exposure to selective serotonin reuptake inhibitors (SSRIs) is very controversial. There is no conclusive evidence for increased risk of malformations after SSRI use in pregnancy. The aim of the study was to determine how fluoxetine is affecting gestation and fetal development in rats. Twenty sexually mature female Wistar rats weighting between 250-260 g received 20 mg/kg body weight fluoxetine from the first day of gestation and during the entire gestation period.The drug was administered by oral route. Healthy, primipareus animals were selected along with 20 female Wistar rats, as control group. Mature males were caged with virgin females for an entire week. Rat’s behaviour during gestation, after birth and rats body weight was examined. The number of healthy pups was also noted. The females not giving birth after 21 days to any pup were anesthetized (halothane through gas scavenging apparatus untilled death) and the gravid uterus were dissected out and examined. Compared to the controlled group, in which weight gain was more significant, the animals from the experimental group had a slight increase in body weight. The weight gain normally induced by gestation, is less significant in fluoxetine treated rats due to the increase serotonin levels in the brain. The uteri examination of pregnant rats showed an increase in the number of dead and resorbed rat embryos. Preclinical studies suggest that the inclusion of fluoxetine in pregnancy category C is justified and the appropriateness of its administration in pregnancy is still an unresolved issue.

Background : The 1st and 2nd degree hemorrhoids is managed non-operatively with the anti-inflammatory and plebothropic drugs. Graptophyllum pictum extract (GPE) has already been used widely in Indonesia to treat hemorrhoid with good result, however, the mechanism is not supported by the molecular research.Objective : This study is intended to study the phlebothropic effects of GPE by measuring the degree of edema and extravassal leucocytes of experimental wistar hemorrhoid.Methods : Experimental study with Randomized Controlled Trial Post-test only design in male wistar rats, weight around 200 gr, induced for the development of a disease-like condition of hemorrhoids by 6% croton oil on the anus for 3 days. Random allocation was performed to divide the 14 wistar rats in 2 groups. Group I as control got normal saline solution, while group II was treated with GPE 100mg/kgbw, started on day 4th for 5 consecutive days. On 9th day blood was extracted from retroorbital fossa and anus was resected up to 2 cm from anal verge and weighted. The degree of anal edema was measured by rectoanal coefficient, that is rasio between anal weight (miligrams) and body weight (grams).Results : Until the end of study, all wistar rat were still alive. The mean (±SD) of body weight   of control group was 173.84 ­(±13.37) and the treatment group was 171.70  (±13.10), and there was no significant differences (p = 0.833). The mean (±SD) of rectoanal coefficient in the treatment group was 2.46 (±0.41) and it was significantly lower than control group  (3.13 ± 0.85) (p = 0.029). The mean (±SD) of extravassal leukocytes in the treatment group was 900.14(±48.09) and it was significantly lower than the control (1003.28 ± 99.30) (p = 0.042).Conclusions : Graptophyllum pictum extract at doses of 100 mg/Kgbw have phlebotonic effect  in decreased edema and extravassal leukocytes.

Background: Diabetes mellitus (DM) is a degenerative disease associated with premature aging characterized by hyperglycemia. Hyperglycemia in people with DM causes oxidative stress and increases Glycated Albumin level, which is the initial precursor to the formation of AGEs. In turn, AGEs will lead to pancreatic β cell damage and apoptosis. Red fruit (Pandanus conoideus L) contains phytochemicals with antioxidant that has the potential to reduce diabetic complications. Therefore, this study aimed to evaluate the effect of metformin and red fruit extract combination toward blood glucose, glycated albumin and pancreatic β cells density in diabetic rats (Rattus norvegicus). Methods: A post-test only control group study was conducted using 36 male Wistar rats as subject. All subjects were induced for type-2 DM with Streptozotocin and Nicotinamide. The diabetic rats were then divided into 2 groups: the positive control group treated with metformin + placebo and the treatment group treated with metformin + red fruit extract. Pancreatic β cell, fasting blood glucose and glycated albumin assessments were performed after 21 days of treatment. Results: The results showed the mean number of pancreatic β cells in the treatment group was higher than the control group (116.11±33.14 vs 83.20±23.94 cells/visual field; p=0.002). But the mean fasting blood glucose in the treatment group was not significantly different compared to the control group (107.67±14.93 vs. 113.67±11.19 mg/dl; p=0.181). The same result also found in the gycated albumin level (Treatment vs control: 6.97±3.63 vs 6.42±4.01 ng/ml; p=0.666). Conclusion: It can be concluded that the administration of red fruit extract increased the density of pancreatic β cell but did not reduce fasting blood glucose and glycated albumin levels in diabetic Wistar rats.

Doxorubicin-induced cardiotoxicity is the leading cause of morbidity and mortality among cancer survivors. The present study was aimed to investigate the cardioprotective potential of methyl gallate; an active polyphenolic nutraceutical, against doxorubicin-induced cardiotoxicity in Wistar rats. Twenty-four female Wistar rats (150–200 g) were divided into four groups (n = 6) which consist of normal control (group I), doxorubicin control (group II), test-A (group III), and test-B (group IV). Group III and group IV animals were prophylactically treated with methyl gallate 150 mg/kg/day and 300 mg/kg/day orally, respectively, for seven days. Doxorubicin (25 mg/kg; single dose) was administered through an intraperitoneal route to group II, III, and IV animals on the seventh day to induce acute cardiotoxicity. On the 8th day, besides ECG analysis, serum CK, CK-MB, LDH, AST, MDA, and GSH were assayed. Following gross examination of isolated hearts, histopathological evaluation was performed by light microscopy. A significant ( p  < 0.05) cardiac injury, as well as oxidative stress, was observed in doxorubicin control rats in comparison to normal control rats. Methyl gallate at both the doses significantly ( p  < 0.05) reduced doxorubicin-induced ECG changes, dyslipidaemia, and elevation of CK, CK-MB, LDH, AST, MDA and increased GSH level. Methyl gallate reversed the doxorubicin-induced histopathological changes in the heart. The present study revealed that methyl gallate exerts cardioprotection against doxorubicin-induced cardiotoxicity in female Wistar rats by suppressing oxidative stress. Our study opens the perspective to clinical studies for consideration of methyl gallate as a potential chemoprotectant nutraceutical in the combination chemotherapy with doxorubicin to limit its cardiotoxicity.

Introduction: Goko cleanser is one of the popular herbal mixtures used by the Nigerian populace. This study was carried out to evaluate the effects of this herbal mixture on some haematological parameters of adult female Wistar rats. Methodology: A total of twenty five Wistar rats weighing about 160 – 280g were divided into five groups according to their corresponding weights. The groups were designated as groups 1 – 5. Group 1 served as the control group, while groups 2, 3, 4, and 5 received 1000mg/Kg, 1500mg/Kg, 2000mg/Kg and 4000mg/Kg respectively. Results: The TWBC, PCV, PLATELET count, and RBC and Hb showed a statistically significant (p<0.05) increase for the test groups 2 – 5 when compared to the control group. The body weight had a statistically significant (p<0.05) decrease in groups 2, 4, and 5; while group 3 had a statistically insignificant (p>0.05) decrease. Conclusion and Recommendation: This study revealed that Goko Cleanser contains some haemopoietic benefits, but inhibit appetite centres. Hence, this study recommends that further study be carried out on the effects of this herbal mixture on the brain so as to reveal the extent of its effect on the appetite centres.

Background: Ultraviolet B exposure is one of the causes of extrinsic skin aging. Ultraviolet exposure may lead to skin collagen damage. This study about mesenchymal stem cells from umbilical cord (UCMSC) compared with platelet rich plasma (PRP) with the aim was to prove that the intradermal injection of UCMSC was more effective than PRP in increasing amount of collagen and fibroblasts in Wistar rats' back skin exposed to Ultraviolet B rays. Methods: This study used post-test only control group design. Subjects were 36 Wistar rats aged 2.5 months. A control group consisting of 18 Wistar rats treated with intradermal injection of PRP and the treatment group with UCMSC. Both groups were exposed to UVB with a total radiation dose of 840 mJ/cm2. The parameter of collagen was determined by picro sirius red staining while fibroblasts by Haematoxylin-Eosin staining. Result: The mean amount of collagen in the control group was lower (57,82±6.52%) than the treatment group (65.69±4.51%) with p<0.001. The result showed there were differences in the number of collagen in both groups (p<0.05). The mean number of fibroblasts in the control group was lower (22.63±5.98 cell/field of view) than the treatment group (28.20±8.90 cell/field of view) with p=0.034. The result showed there were differences in mean of fibroblasts in both groups (p<0.05). Conclusion: It can be concluded that the intradermal injection of UCMSC was more effective in increasing the amount of collagen and fibroblasts than intradermal injection of PRP in Wistar rats' back skin exposed to UVB rays.
