Abstract Background Garcinia lanceifolia Roxb. has been used by many ethnic communities of Northeast India to mitigate various disorders like dyspepsia, ulcers, diabetes, etc. However, a robust scientific study on its antidiabetic and antiulcer potential is unavailable till date. The aim of this present study is to scientifically validate if the antidiabetic and antiulcer effects reported by the ethnic tribes of Assam has any scientific value or not. The effects were tested in adult Wistar albino rats using approved animal models for preclinical testing of pharmacological activities. Results The hydroalcoholic extract of the bark of Garcinia lanceifolia Roxb. was prepared and its LD50 was calculated. The LD50 was determined to be greater than 5000 mg/kg body weight. The extract at doses of 250 mg/kg body weight and 500 mg/kg body weight was found to exhibit a very potent dose-dependent antidiabetic activity. The results were backed by a battery of test including analysis of serum levels of blood glucose, lipid profiles, in vivo antioxidant enzymes, and histopathological studies. Evidence of dose-dependent antiulcer activity of the extract was backed by robust scientific data. It was found that HAEGL induced a significant dose-dependent increase in the ulcer index in both alcohol-induced and acetic acid-induced ulcer models, which was evident from the macroscopic observation of the inner lining of the gastric mucosa and the histological evaluation of the extracted stomach. Conclusion The results suggested that the bark of Garcinia lanceifolia (Roxb.) has significant antidiabetic and antiulcer potential. Further studies with respect to the development herbal dosage forms and its safety evaluation are required.

Antidiabetic activity of 95% and 50% ethanol extracts of C. macrophylla roots was evaluated using male Wistar albino rats to gather support for the promising results of glucose uptake against normal control in studies conducted on L-6 muscle cell lines as well as isolated rat hemidiaphragm. Initially, preliminary phytochemical studies were performed and identified the presence of phenolics, flavonoids and their glycosides. Before doing in vivo experiment, by following RRR concept, glucose uptake in L-6 muscle cell lines were performed, detected better glucose uptake against normal control and decided to do in vivo experiments. The estimation of glucose uptake in isolated rat hemidiaphragm treated with the extract was employed for the study of peripheral glucose uptake and the results were significant. Content of blood glucose was high in STZ-diabetic rats as compared to normal rats. Treatment of STZ-diabetic rats with the test extract ME -CM RH significantly reduced the hyperglycaemia when compared with STZ only treated rats. Rats lost their body weight after STZ treatment, which was reversed by the treatment of test extracts and gliclazide. HbA1C levels were higher in the STZ-induced diabetic rats compared to the normal control rats. Treatment with ME-CMRH (methanol eluate – CMRH) decreased the HbA1C level of the STZ induced diabetic rats. Antidiabetic activity of the test extract ME-CMRH at 500 mg/kg body weight dose was comparable with the effect produced by the standard drug gliclazide in restoring the levels of blood glucose, body weight and HbA1C towards normal levels. The above data are indicative of the antidiabetic potential of C. macrophylla roots. In the evaluation of mechanism of action by gene expression studies, upregulation of Glut-4 as well as PPAR-γ were demonstrated.

Background: Peptic ulcer is a deep gastrointestinal erosion disorder that involves the entire mucosal thickness and can even penetrate the muscular mucosa. Nowadays, several plants and compounds derived from it have been screened for their antiulcer activity. In the last few years, there has been an exponential growth in the field of herbal medicine. This field has gained popularity in both developing and developed countries because of their natural origin and less side effects. Objective: This review aims to provide a comprehensive summary of currently available knowledge of medicinal plants and phytoconstituents reported for their anti-ulcer properties. Methods: The worldwide accepted database like SCOPUS, PUBMED, SCIELO, NISCAIR, ScienceDirect, Springerlink, Web of Science, Wiley, SciFinder and Google Scholar were used to retrieve available published literature. Results: A comprehensive review of the present paper is an attempt to list the plants with antiulcer activity. The review narrates the dire need to explore potential chemical moieties that exert an antiulcer effect, from unexploited traditional plants. Furthermore, the present study reveals the intense requirement to exploit the exact mechanism through which either the plant extracts or their active constituents exhibit their antiulcer properties. Conclusion: This article is the compilation of the plants and its constituents reported for the treatment of peptic ulcers. The Comprehensive data will surely attract the number of investigators to initiate further research that might lead to the drugs for the treatment of ulcers. As sufficient scientific data is not available on plants, most of the herbals cannot be recommended for the treatment of diseases. This can be achieved by research on pure chemical structures derived from plants or to prepare new lead compounds with proven beneficial preclinical in vitro and in vivo effects. However, a lot remains to be done in further investigations for the better status of medicinal plants.

Various parts of psidium guajava linn are used in ethnomedicine in controls and treatments of different disorders such as liver, heart, and blood related disorders [11]. This research work investigate qualitative phytochemical composition of ethanol leaf extract of psidium guajava linn and its effect on some hematological parameters in albino rats. Qualitative phytochemical analysis of the extract was performed by standard procedures. A total of 20 adult male albino rats were used, they were randomly placed into 5 groups (A, B, C, D and E) each group containing 4 rats groups A, B, C, and D were administered, via oral intubation, the extract at doses of 200, 400, 600, and 800 mg/kg body weight respectively of the extract for 7 consecutive days. Phytochemical screening shows that the extract was rich in tannins anthraquinones, and flavonoid while alkaloids, saponins, terpenes and glycoside were slightly present. There was a decrease in the average body weight, physical activities, and feed and water intake of the rats in the test groups relative to the control hemoglobin concentrate, total white blood cell and packed cell volume recorded in the groups  administered the extract were significantly (p<0.05) higher than in the control this effect on  the haemotological parameters was found to be dose dependent. The findings of this study suggest that the aqueous extract of the fruit plants may be useful in control and treatment of blood related disorders.  These useful applications may be as a result of the phytochemical present in the extract.

Objective: In vitro antioxidant activity, in vivo antidiabetic property and intestinal attachment by two potential probiotic bacterial strains, namely, Enterococcus faecium and Enterococcus hirae were studied using albino rats. Methods: Antioxidant the activity was assessed using 2,2-Diphenyl-1-picrylhydrazyl radicals scavenging assay. Alloxan was administered intraperitoneally to induce diabetic conditions in experimental rats. Animals were treated with oral administration of Enterococcus spp., such as E. faecium, and E. hirae isolated from goat and sheep milk. The control animal group received normal saline for the same days. Glibenclamide drug was used as a positive control against probiotic bacterial cells. Results: However, administration of probiotic bacterial strains E. faecium and E. hirae, in albino rats significantly (p<0.05) at varying doses lowered blood glucose levels in diabetic rats as compared to the diabetic control group. Both the species of Enterococcus increased the bodyweight of experimental rats. However, E. faecium was the best antidiabetic strain having the antioxidant activities also in comparison to E. hirae. The attachment of probiotic bacterial cells E. faecium on the rat’s intestine wall against pathogens was examined. Furthermore, E. faecium showed its aggregation with pathogens by attachment of the intestines of albino rats. This showed that both the bacterial strains exhibited in vivo antidiabetic effect. Conclusion: The results of this study showed that probiotic bacteria possess antioxidant, antidiabetic activities, and attachment of intestine.

The main aim of this study was to screen the selected fruit peel extracts and their polyherbal mixture (PHM) for hepatoprotective activity. Male wistar albino rats (180-200 g), divided into 12 groups after induction of hepatotoxicity, were treated with selected fruit peel extracts and PHM and at the end of 14th day blood and liver samples were collected and analysed. The aqueous peel extract of Malus pumila was a better hepatoprotective among the selected peel extracts. The activities might be due to the conditioning of hepatocytes by protecting the integrity of the membrane from CCl4 induced leakage of serum markers into circulation. All the selected plant extracts and PHM were shown to revert back the liver enzymes to the normal values in diseased rats in a dose dependent manner. In conclusion, the selected fruit peel extracts and poly herbal mixture can be a potent hepatoprotective agent due to their antioxidant and anti-inflammatory actions.

Abstract To determine the biologic activity of interleukin-6 (IL-6) on megakaryocytopoiesis and thrombocytopoiesis in vivo, the cytokine was administered intraperitoneally to mice every 12 hours at varying doses for five days or for varying time intervals, based on the kinetic analysis of IL-6 serum levels indicating the peak of 40 minutes following injection, with no detection at 150 minutes. A dose-response experiment showed that IL-6 increased platelet counts in a dose- dependent fashion at a plateau stimulation level of 5 micrograms. Administration of 5 micrograms of IL-6 reproducibly elevated platelet counts at five days by approximately 50% to 60% of increase. Moreover, a striking increase in megakaryocytic size in response to IL-6 was elicited by the treatment, but no change in megakaryocyte numbers; whereas IL-6 administration did not expand CFU-MK numbers. The in vivo studies in this manner had negligible effects on other hematologic parameters, with the minor exception of monocyte levels. These data show that IL-6 acts on maturational stages in megakaryocytopoiesis and promotes platelet production in vivo in mice, suggesting that IL-6 functions as thrombopoietin.

Objective: Hepatic cancer is known as primary liver cancer and hepatocellular carcinoma (HCC). Newly silver nanoparticles gained importance due to its advantages and multiple potential such as molecular imaging agent, antimicrobial, wound healing, anti-inflammatory and anticancer activity. The current study deals to assess therapeutic property silver nanoparticles (AgNPs) against diethylnitrosamine (DENA), and carbon tetrachloride (CCL4) induced hepatic cancer. Methods: Thirty male albino rats (200-250g) were distributed into four groups and hepatic cancer was induced with a single intraperitoneal dose of 200 mg/kg body weight of DENA. Two weeks later, animals received subcutaneous injections of CCl4 once a week in a dose of 3 ml/kg body weight for 6weeks. Serum biomarkers, antioxidants enzymes, inflammatory markers were evaluated to find the anti-proliferative potential of silver nanoparticles. Histological evaluation and microscopic reports were also done to document the results of the current work. Results: AgNPs significantly recover the serum marker enzymes of hepatic parameter AST, ALT, ALP, and total bilirubin and also decreased the levels of NO, IL-6 and TNF-α. Histopathological features also exhibited recovery of a hepatic architecture in cancer-induced rats. Moreover, the immunohistochemical investigation demonstrated that the levels of PCNA, and Caspase-3, which are hepatocarcinogenic markers, were significantly improved by AgNPs. Conclusion: These results concluded that AgNPs showed promising curing effects on hepatocellular ailments.

ABSTRACT This study describes sensitive immunoenzymometric assays (IEMAs) for chicken avidin and ovalbumin, markers of cytodifferentiation and action of progesterone and oestrogen in the oviduct magnum mucosa. The determination range was 0·5–100 ng/ml and the detection limit 0·1 ng/ml in both IEMAs. The intra- and interassay coefficients of variation, measured from chicken tissue supernatants, averaged below 6 and 10% respectively. IEMAs correlated well with the radioimmunoassays for avidin and ovalbumin previously developed in our laboratory, and with the widely used [14C]biotin-binding method for avidin. Using an IEMA, we found avidin induction with low concentrations of progesterone in the differentiated oviduct of oestrogen-pretreated chicks. The induction has not been detected previously by less sensitive methods. Avidin was induced by all given doses of progesterone (0·2–200 mg/kg in vivo for 24 h after a short oestrogen treatment), the response being dose-dependent at doses of 0·2–20 mg progesterone/kg body weight, the maximum avidin production being about 70 μg/g tissue. Ovalbumin was induced at doses of 2–200 mg progesterone/kg body weight without variations in the responses, being about 35 mg/g. The mean content of avidin in the oviduct of laying hens was 58·1 μg/g, and of ovalbumin 74·9 mg/g. Minimal traces of avidin and ovalbumin were found in the oviduct after hatching (0·3 and 5 μg/g respectively); however, progesterone did not have an effect on this expression. Sensitivity, rapidity and practicability, together with non-radioactivity, are the main advantages of the present IEMAs for chicken avidin and ovalbumin. Journal of Endocrinology (1991) 130, 191–197
