Teratogenic Potential of Solenstemma argel Extract in Wistar Albino Rats

The majority of people in Africa receive their basic health care through herbal treatments. Herbal medicine may negatively impact fetal development irreparably. This study examined the teratogenic potential of Solenstemma argel extract in pregnant rats. Pregnant rats were treated with Solenstemma argel from 7th to 16th day of gestation. The dosage used was 250 mg/kg, intraperitoneal.Solenstemma argel extract treated group showed fetal abnormalities appeared as body hemorrhage, limbs abnormalities and resorption of fetuses. These appears in 25% of the fetuses (P-value = 0.01) which is significantly differed from control group. Furthermore, histopathological findings of liver sections from fetuses of Solenstemma argel - treated mothers showed loose liver texture and hepatocytes hemorrhage.In this study, we conclude that the use Solenstemma argel extract during the organogenesis period in pregnant rats has the potential to cause teratogenic effects, as well as abnormalities in liver histopathology.

The Contribution of Sex Difference on Different Liver Histopathology Between Male and Female Mice After Oral Administration of Caffeine

Background : There are several studies reporting the effect of caffeine on liver histopathology, but it remains controversy. The laboratory animal used in those studies were predominantly male, whereas there is contribution of sex difference on different liver reaction to xenobiotic between male and female subject. Objective : It is necessary to conduct a study to explore the differences between the liver histopathology of male and female mice after oral administration of caffeine. Methods : This study used 36 mice (Mus musculus) that were divided into 4 groups: male & female untreated groups and male & female treated groups which were orally administered with caffeine 0.4 mg / 20 gramBW daily for 30 days. At the end of treatment, mice were euthanized and dissected. Histopathological examination was done to determine the percentage of liver cell death of each group. Results: The percentage of liver cell deathin female treated group was higher than male treated group (p = 0.0001). But there was no significant difference of liver cells death between male control and treated group and between female control and treated group. Conclusion : There was significant difference in liver histopathology between male and female mice after oral administration of caffeine.

Protective effect of a new generation of activated and purified bentonite in combination with yeast and phytogenic substances on mycotoxin challenge in pigs

The study aimed to investigate the efficacy of new mycotoxin adsorbents based on purified and activated bentonites combined with yeast and phytogenic compounds in fattening pigs. The experiment involved 96 pigs (31.2±2.4 kg). Control (C) group was fed a diet naturally contaminated with mycotoxins (5 mg/kg deoxynivalenol, DON) without an adsorbent. Treated groups received the feed with mycotoxin adsorbents: purified and activated bentonite (T1), purified and activated bentonite, yeast derivatives, phytogenic substances (T2), and purified, activated, and sulphurated bentonite with phytogenic substances (T3). Evaluated parameters involved growth performance, organ weight, small intestine and liver histopathology, complete blood count, serum biochemistry, antioxidant status of the organism and total and free DON content in urine. In all treated groups, an significant increase in intestinal GSH and GSH/GSSG ratio was observed when compared to C. No significant effects on liver and kidney weight, complete blood count, serum or intestinal malondialdehyde concentration, or total/free DON content in urine were observed. All adsorbents improved histopathological findings in the liver when compared to C. Moreover, T1, and T2 groups showed no presence of inflammatory reaction or necrotic changes in the livers. Although, mycotoxin adsorbents investigated in this study had no significant impact on pig growth performance, they reduced the oxidative stress, and on the tissue level they protected the jejunal tissue and liver parenchyma under deoxynivalenol challenge.

The antihyperlipidaemic and hepatoprotective effect of Ipomoea batatas L. leaves extract in high-fat diet rats

The administration of high-fat diets can increase the body's lipid level and damage the organs. Purple sweet potato leaf (Ipomoea batatas L.) was reported as an antioxidant against free radicals. This study aimed to observe the sweet potato leaf extract's activity on decreasing lipid profile and hepatoprotective effect in high-fat diet fed rats. The treatment animals were divided into five groups, namely normal control, high-fat diet (HFD) control, the treatment group of purple sweet potato leaf extract (SPLE) doses 100 mg/kg BW, 200 mg/kg BW and 400 mg/kg BW which fed with high-fat diet for 14 days and SPLE for 28 days. After treatment was completed, the blood was collected for the detection of cholesterol, triglyceride, serum glutamic oxaloacetic transaminase (SGOT), and serum glutamic pyruvate transaminase (SGPT). After that, the animals were sacrificed, and a liver histopathology observation was conducted using Haematoxylien and Eosin staining. The result showed a significant decrease in cholesterol and triglyceride levels (p≤0.05) compared to the negative group in all treated groups. The SGOT and SGPT enzymes in all of treatment groups were also found to decrease compared with HFD control. The result was confirmed by the histopathological observations. The finding suggested the potency of SPLE for antihyperlipidaemic and hepatoprotective agent.

Metabolome Characteristics of Liver Autophagy Deficiency under Starvation Conditions in Infancy

The liver function is essential for metabolism, detoxification, and bile synthesis, even in the neonatal period. Autophagy plays significance roles in THE adult liver, whereas the role of liver autophagy in the early neonatal period largely remains unclear. To clarify the importance of liver autophagy in the neonatal starvation period, we generated liver-specific autophagy-deficient (Atg5flox/flox; Albumin-Cre) mice and investigated under starvation conditions comparing with control (Atg5flox/+; Albumin-Cre) mice, focusing on serum metabolites and liver histopathology. As a result, autophagy in the liver was found to unessential for the survival under postnatal starvation. A metabolomics analysis of serum metabolites by gas chromatography-tandem mass spectrometry showed a significant difference between the groups, especially after 12-h starvation, suggesting the synergistical adaption of metabolic pathways, such as the “malate-aspartate shuttle”, “aspartate metabolism”, “urea cycle”, and “glycine and serine metabolism”. Liver-specific autophagy-deficiency under postnatal starvation conditions can cause a characteristic metabolic alteration suggesting a change of the mitochondrial function. Neonates seemed to maintain ketone production under starvation conditions, even in the autophagy-deficient liver, through a change in the mitochondrial function, which may be an adaptive mechanism for avoiding fatal starvation.

Effect of Probiotic Supplementation on Sprague Dawley Rat Liver Histopathology Fed by High Fat High Fructose Diet

Background: Non-alcoholic fatty liver disease (NAFLD) is an important cause of liver disease burden worldwide. The gastrointestinal microbiota has a close relationship with the liver as the liver is most exposed to intestinal bacteria. Microbial manipulation is a potential and effective therapy as an alternative in the management of NAFLD/NASH. It has been found that probiotics prevent NAFLD/NASH. However, the study about the protective effect of probiotics on NAFLD/NASH is still limited. Objective: The objective of this study is to evaluate the effect of probiotics on liver histopathology Sprague Dawley rats which given high-fat high fructose (HFHFr) dietMethods: This study is a murine-model post-test-only control study group design. The samples were 21 Sprague Dawley male rats in 7 – 8 weeks of age and were divided into three groups. The Control Group (C) was provided with a standard chow diet for eight weeks. The Non-Probiotic (NP) group was given a High-Fat High Fructose (HFHFr) diet for eight weeks. The Probiotic group (P) was given a HFHFr diet for eight weeks, and a combination of HFHFr and probiotic supplementation consisted of Lactobacillus acidophilus, Bifidobacterium longum, and Streptococcus thermophilus for the next eight weeks. Histopathological samples were obtained from liver biopsy to assess steatosis, NAFLD activity score (NAS), and fibrosis stages. Wilcoxon test was done to analyze body weight before and after treatment. We analyzed the difference in histopathological results using the Mann-Whitney test.Results: We found a significant difference in NAFL and NAS Score between NP and P group. The P group was shown to have lower trends for NAFLD and NASH than the NP group, but not for fibrosis. There is no significant difference between pre and post-test body weight. Conclusion: Probiotics supplementation has a protective effect on liver histopathology against disturbances caused by the HFHFr diet.
