Introduction: Kalanchoe pinnata extracts have been shown to possess beneficial cardiovascular effects, analgesic and myorelaxant activities. This study aimed at evaluating the haematological and anti-fatigue effects of its aqueous extract. Materials and methods: This was an in vivo pharmacological experiment, carried out in the Laboratory of Zoology, University of Buea, from January to May 2018. A total of 48 mice were subjected to a 90mins/day-free endurance swimming test for 14 days. Two groups of mice received distilled water and 12% NaCl solution, respectively. Five groups received the plant extract (25, 50, 100 and 200 mg/kg/day) and 200mg/kg/day+NaCl. One positive control group received 5% Vitamin C (1.97mg/kg/day). All administrations were by gavage. Maximum swimming time, glycaemia, lactatemia, uremia, triglyceridemia, haematological indices, tissue glutathion peroxidase, malondialdehyde, glucose and creatine kinase-MB in the heart or gastrocnemius muscle were measured. Results: K. pinnata (50 and 100mg/kg/day) induced a non-significant increase of the swimming duration, compared to neutral control. However, the 12%NaCl group recorded a significant (P<0.05) increase. In the blood, NaCl induced a decrease of platelets that was significantly reverted by the extract in the 200mg/kg+NaCl group. The extract prevented the increase of the level of CK-MB in NaCl group and decreased the serum triglycerides, glucose, urea nitrogen and Lactate levels. In the tissues, MDA and CK-MB levels significantly increased (P<0.001) in the negative control. These increases were significantly (P<0.001) prevented by K. pinnata (200mg/kg/day). Conclusions: Significant biochemical variations support the hypothesis that K. pinnata could be used to delay exercise induced fatigue.

this study included the using of the mixture of alcoholic extract Peganum harmala seeds and cones of Cupressus sempervirens at concentrations (1+50) mgml. And then experimentation on the mice injected with protoscolices and its comparison with the mice injected with only protoscolices (as positive control group), and the mice injected with normal saline (as negative control) to investigate the effect of plant mixture in vivo, it appeared of getting the reduction of hydatid cyst with percentage 100% in processed group with the mixture compared with positive group as its absence of the hydatid cyst in processed group. The lowering significantly occurred in the averages of the weights of the liver and spleen and the averages of its distension in processed groups and about of the positive group and which was approach to the negative group. Also study the tissular changes occurred in the liver and spleen, in the liver it occurred of changes in the liver cell and increase in the number of the kupffer cell as a defensive in the processed group were less than what it appeared in the positive control, but the spleen, it appeared the dilation of the whit pulp and the appearance of the cell composing of the hemic platelets (megakaryocyte cells) in the mice processed in comparison with negative control. These changes were of less acuity in the group processed. Thus from the results of this study at appeared the possibility of using the mixture in vivo in successful and safe way by it a capability of initiating the immunity system to the inhibition of the protoscolices and prevent the development of the secondary hydatid cyst in vivo without causing the negative side effect.

Abstract Background: In traditional medicine, the floral diversity permits the inhabitants of North Cameroon to use a great number of plants to fight against Malaria. The aim of this study was to identify plants used in traditional medicine to treat malaria, and to verify the scientific basis for the use of one of these plants in the locality of Gamba.Methods: An Ethnopharmacological survey was carried out on 15 traditional healers. We collected data on use of medicinal plants using questionnaires. Then in-vivo antimalarial activity of the decoctioned and macerated aqueous extracts of khaya senegalensis trunk bark was evaluated. The 4-day suppressive peters test was realised on mus musculus swiss albino mice. On day one, mice were infected with 107 plasmodium berghei parasitized red blood cells through intra-peritoneal inoculation. 2 hours after infestation, mice in batches of 6 were treated orally at a dose of 75, 150.300 mg/Kg for macerated aqueous extract and 65, 120.260 mg/Kg for decoctioned extract daily during 3 days at an administration volume of 10 ml/Kg. An extract was considered (% reduction): Highly active (between 100-90 %); moderate (between 90-50 %); weak (between 50-10 %); Inactive (between 0 %). P-values <0.05 were considered statistically significant.Results: A total of 18 plant species belonging to 12 families were identified for the preparation of 12 recipes. The decocted aqueous extract of khaya senegalensis showed moderate anti-plasmodial activity (% reduction = 52.46%) at the highest dose of 260 mg/kg with p<0.001 compared to the positive control group. The aqueous macerate at doses of 150 and 300mg/kg gave respectively a percentage reduction of parasitaemia of 59.42% and 71.80% and also showed moderate anti-plasmodial activity; with p<0.001 between the different extracts and the positive control (99.18%).Conclusion: In conclusion, extracts of khaya senegalensis showed moderate anti-plasmodial activity. It would therefore be necessary to evaluate the anti-malarial activity in-vivo and the toxicity of the aqueous extracts macerated using other solvents and also test the other plants listed.

Background: The present study was performed to explore whether the aqueous extract of Senecio biafrae (S. biafrae) roots provide any in vivo protective activity against carbon tetrachloride (CCl4)-induced hepatotoxicity in male albino rats. Methods: Rats (150-200 grams) were grouped into five groups (A-E) of six rats each and were treated orally for twelve days with 72 hourly administration of CCl4 (1 mL/kg) as follows: Group A received distilled water only (negative control), Group B was administered distilled water plus CCl4 (positive control), Group C was administered 400 mg/kg extract and CCl4, Group D received 200 mg/extract and CCl4, while Group E was administered standard drug (Silymarin 25mg/kg, PO). Results: Pre-treatment with the extract of S. biafrae (200 or 400mg/kg) or Silymarin (25mg/kg) caused significant restoration in the biomarkers as evaluated by reducing the levels of malondialdehyde, transaminases and elevating the levels of superoxide dismutase, catalase and glutathione peroxidase activities, which were altered by CCl4 toxicity. The extract at a dose of 400mg/kg demonstrated similar activities comparable to the standard drug (Silymarin). Conclusion: The results of this study indicate that the root extract of S. biafrae possesses hepatoprotective and anti-oxidant properties which may be due to the presence of phytochemicals in it.

Background: Although scientific studies have confirmed the action of homeopathic high dilutions in living organisms an endless debate on the choice of the most fitting dilution, the frequency of administration and the dose (amount of medicine) still remains. Aims: This study sought to assess the in vivo effect of 2 different concentrations of Arsenicum album 30cH in order to elucidate some problems in the homeopathic notion of dose. Methods: Male Wistar rats previously intoxicated with sodium arsenate by peritoneal injection were treated with undiluted Ars 30cH and Ars 30cH in 1% solution administered by oral route. Atomic absorption spectroscopy was employed to measure the levels of arsenic retained in the animals as well as the amounts eliminated through urine. Urine samples were collected before and after and during treatment. A positive control group (intoxicated animals) and negative control group (non-intoxicated animals) were administered only the vehicle used to prepare the medicine (ethanol). Results: The groups treated with undiluted Ars 30cH and Ars 30cH in 1% solution eliminated significant amounts of arsenic through urine when compared to the control groups. The group treated with undiluted Ars 30cH eliminated significantly higher amounts of arsenic than the group treated with the same medicine in 1% solution. Conclusion: These results suggest that undiluted Ars 30cH was more effective than in 1% solution in this experimental model.

Lactobacillus plantarum (LAB) is a group of lactic acid bacteria that can produce exopolysaccharide (EPS). The objective of this study was to determine the effect of adding selenium chloride oxide (SeOCl2) to the increased immunomodulatory potential of EPS L. plantarum Y-1.2. The experiment was conducted in vivo using macrophage cells of peritoneal fluid of mice induced by Staphylococcus aureus. EPS was obtained by precipitation at 4 °C. Identification test using HPLC showed that crude EPS of L. plantarum Y-1.2 containing glucose monomers for value retention times 4.198 and 4.204, crude EPS approaches the retention time of glucose BP 4.234. Testing of immuno-modulatory divided into six treatment groups. Group 1-3 as the control group, a positive control (Stimuno), negative control (crude EPS 50 mg/kg BW in mice), normal control (distilled water). Group 4-6 as the test group was given crude EPS 50 mg/kg BW in mice and selenium oxide chloride doses of 0.13 µg; 0.26 µg; 0.52 µg. The test results showed a dosage of 0.52 µg selenium chloride oxide to crude EPS of 50 mg/kg BW in mice could increase the activity and phagocytic capacity amounted to 28.06% and 28.39%

Aim:: The present work was aimed to find out the anti-allergic activity of ethanol extracts of Quisqualis indica Linn. (EEQI) by in-vitro and in-vivo murine models. Background:: Worldwide, the rise in prevalence of allergic diseases has continued in the industrialized world for more than 50 years. Worldwide, 0.05–2% of the population is estimated to experience anaphylaxis at some point in life. Quisqualis Indica Linn in an ornamental plant that have been rarely used as a herbal medicines, however presence of polyphenols and flavonoids have been reported to possessed anti-inflammatory, antipyretic and immunomodulatory activity which have some pathological relevance with anaphylaxis. Objective:: The objective of the present research was to investigate, scientifically explored and understand the probable antianaphylactic mechanism of ethanol extracts of Quisqualis indica Linn. via different preclinical models. Material and Method:: In-vitro study was done on de-granulated mesenteric mast cells induced by compound 48/80 and invivo study was done by passive cutaneous anaphylaxis (PCA) model. In the in-vitro study degranulated mesenteric cells were grouped into negative control (compound 48/80 treated), positive control (Disodium cromoglycate + 48/80 treated) and 3 test groups (EEQI 10 μg/ml + 48/80 treated, EEQI 50 μg/ml + 48/80 treated and EEQI 100 μg/ml + 48/80 treated). The number of degranulated mast cells was counted and compared within the different treatment groups. In the in-vivo study the rats were first grouped into negative control (vehicle only), positive control (Disodium cromoglycate) and 2 test groups (EEQI: 100 and 200 mg/kilogram). The animals were pretreated for 12 days. On the 12th day all the rats were immunized with serum anti-ovalbumin (obtained from an already sensitized rat) by the intradermal route. After 24 h of serum injection, Evans blue dye containing oval albumin was administered intravenously in all groups. Three days later, the rats were taken down for the severity of the anaphylactic reactions. Result:: EEQI significantly attenuate mast cell degranulation and maintain the cell intactness as compared to control (P < 0.001). It was set up to support the degree of anaphylaxis as compared to control group (P < 0.001). Conclusion:: The outcomes of the work revealed the preventive effect of Quisqualis indica Linn. against allergic manifestations.

Abstract Diabetic pregnancies are cleary associated with maternal type 2 diabetes and metabolic syndrome as well as atherosclerotic diseases in the offspring. The global prevalence of hyperglycemia in pregnancy was estimated as 15.8% of live births to women in 2019, with an upward trend. Numerous parental risk factors as well as trans-generational mechanisms targeting the utero-placental system, leading to diabetes, dysmetabolic and atherosclerotic conditions in the next generation, seem to be involved within this pathophysiological context. To focus on the predictable impact of trans-generational diabetic programming, we studied age- and gender-matched offspring of diabetic and nondiabetic mothers. The offspring generation consists of three groups: C57BL/6-J-Ins2 Akita (positive control group), wild-type C57BL/6-J-Ins2 Akita (experimental group), and C57BL/6-J mice (negative control group). We undertook intraperitoneal glucose tolerance tests at 3 and 11 weeks of age. Moreover, this in vivo model was complemented by a corresponding in silico model. Although at 3 weeks of age, no significant effects could be observed, we could demonstrate at 11 weeks of age characteristic and significant differences in relation to maternal diabetic imprinting based on the in silico model-based predictors. These predictors allow the generation of a concise classification tree assigning maternal diabetic imprinting correctly in 91% of study cases. Our data show that hyperglycemic in utero milieu contributes to trans-generational diabetic programming leading to impaired glucose tolerance in the offspring of diabetic mothers early on. These observations can be clearly and early distinguished from genetically determined diabetes, for example, type 1 diabetes, in which basal glucose values are significantly raised.

 Objectives: To analyze the effectiveness of the topical application of a standardized ethanol extract of roselle calyx in the treatment of oral mucous ulceration.Methods: Twelve Sprague Dawley rats were divided into two groups, with oral mucous ulcer being induced in all the rats. The ulcer diameter, reddish color, and the swollen membrane around the ulcer, as well as the inflammation score of the ulcer, were recorded for all animals. The negative control group was treated with aquades, while the positive control group was treated with 0.1% triamcinolone acetonide. The treatment group received the topical application of 7.5% and 15% standardized ethanol extract of roselle calyx twice a day for 3 or 7 days. On the 4th day, six rats were sacrificed, while the remaining six rats continued to receive treatment as before. On the 8th day, all the rats were sacrificed. Specimens were fixed, and histology slides were made. Further, microscopic slides were observed and scored.Result: Both the 7.5% and 15% standardized ethanol extracts of roselle calyx were found to reduce the ulcer diameter and inflammation score. No swelling or redness was observed.Conclusions: The application of 7.5% standardized ethanol extract of roselle calyx for 7 days is equally as effective as the application of 0.1% triamcinolone acetonides, except in terms of the decrease in the inflammation score.
