Cancer is being regarded as a malignant ailment emerging from unrestricted cell division occurring in the body to make mass of tissues. Spondias mombin L. (Family- Anacardiaceae) grows in coastal areas and in the rain forest into a big tree of up to 15 – 22 m. This study investigated the efficacy of S. mombin aqueous and n-hexane extracts in chemically induced tumor-bearing animals.Experimental: Twenty-eight (28) healthy rats were used and grouped into seven (7). Six groups were induced with trichloroacetic acid and ethidium bromide leaving out normal control group for 28 days prior to treatments. LBH589 (standard anticancer drug, 500 mg/kg) served as positive control. At the termination of the experiments, the animals were sacrificed; solid tumor volume was determined, blood and tissue samples were collected for hematology and histopathology respectively.Results: The results showed very significant reduction in the solid tumour volumes of S. mombin leaves extracts treated groups compared to positive and untreated control groups. The result of hematological parameters showed that the hemoglobin content, red blood cell and white blood cell counts of all treated groups were near to normal control group. Normal histological features were observed in control group animals, the negative groups showed the manifestations of cancer, all the treatment groups showed significant levels of repair almost similar to normal features in control group particularly in intestines and lungs of the experimental animals.Recommended applications/industries: The present data provided substantial evidence that S. mombin leaves suppressed tumor growth in experimental animals and suggested that the extracts are potential antitumorigenic agent inhibiting chemically induced lung and intestinal tumors.

In the study of antioxidant power, plant leaf extract with 48.66±5.5 μg was able to inhibit 50% of DPPH radicals, which had a weaker ability than synthetic antioxidants. The leaf extract of the plant had a higher ability than the synthetic antioxidant BHA to inhibit nitric oxide radicals and its ability was as high as BHT. The ability to inhibit the linoleic acid peroxidation of leaf and flower extracts at the beginning of the functional test showed similar BHT and BHA, at the end, the ability of leaf extract was stronger than BHA and weaker than BHT. The inhibitory potential of malondialdehyde leaf extract (82.66±1.5%) was better than BHA and weaker than BHT. Pearson correlation coefficients between phenolic content and antioxidant capacity of samples were high. Examination of leaf essential oil using GC-MS technique showed the presence of phenolic compounds in the plant.Recommended applications/industries: Due to the dangers of synthetic antioxidants in the food industry, the results of this study could introduce another application of this plant in terms of strong antioxidant properties.

Osteoporosis is known globally as a severe health problem affecting approximately 200 million people worldwide. Therefore, a pharmacological solution is urgently needed. Studies have shown that farnesyl pyrophosphate synthase is a crucial enzyme in the mevalonate pathway that causes bone resorption, thus serving as a key pharmacological target.Experimental: Gongronema latifolium’s (Benth) phytoconstituents were screened against the mevalonate pathway enzyme farnesyl pyrophosphate synthase computationally using molecular docking, pharmacokinetics screening and Molecular Mechanics/Generalized Born Surface Area approach to identify compounds with the better inhibitorypotentials against this target in this study.Results: The study resulted that five compounds; hyperoside, rutin, epigallocatechin-3-gallate, kaempferol-3-arabinoside, and isoquercetin show a better inhibitory potential by binding to the active site of farnesyl pyrophosphate synthase compared with a co-crystalized ligand. These hit compounds were further subjected to pharmacokinetics studies to predict their drug-likeness and toxicity characteristics which show that all hit compounds except Rutin are drug-like leaving Kaempferol-3-Arabinoside as the most drug-like hit compound compared to the co-crystallized ligand.Recommended applications/industries: This study suggests that G. latifolium leaf could be a good plant source for a drug-like compound that may treat osteoporosis by inhibiting the farnesyl pyrophosphate synthase, in the mevalonate pathway, thereby stopping bone resorption.

Groups F, G, and H received KBrO3 with AEAC at 150 mg/kg, 300 mg/kg, and quercetin, respectively, on alternate days for 3 months.Results: The phytochemical analysis of the AEAC revealed the presence and absence of some phytochemical constituents. The Acute toxicity result indicated that AEAC has an LD50 above 5000mg/kg. KBrO3 caused a significant (P<0.05) decrease in the haematological parameters relative to the control but administration of KBrO3 with AEAC or quercetin improved the parameters. KBrO3 caused a significant (P<0.05) increase in the levels of triglycerides (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C), but significantly (P<0.05) lower level of HDL-C. Treatment with KBrO3 and AEAC or quercetin significantly (P<0.05) abrogated these KBrO3-induced alterations. Similar ameliorative effects of AEAC were found in KBrO3-induced alterations in atherogenic indices, such as Castelli's Risk Index I (CRI-1), Castelli's Risk Index II (CRI-II), Atherogenic Coefficient (AC), and Atherogenic Index of Plasma (AIP) indices relative to the control.Recommended applications/industries: According to the present results, AEAC showed amelioration against KBrO3-induced derangement in the haematological, lipid, and atherogenic indices and it might be helpful in the management of cardiovascular problems.

Because of poor blood flow and the possibility of adhesions during repair, tendon injury management is particularlyimportant.Therefore, finding a quick way to repair tendon tissue is one of the targets that has been pursued over the years.Experimental: In this study, 24 male rats were divided into 4 groups, including first group without any treatment, second group receiving dexamethasone (1mg/kg), third group receiving 250 mg/kg Viola odorata and Pistacia atlantica extract, fourth group receiving 500 mg/kg and Pistacia atlantica and Viola odorata extract. After anesthesia of rat acute tendonitis developed. Al the mentioned groups were injected subcutaneously on bigining day, 7 and 21 days after surgery and histopathological evaluation was performed on day 21.Results: The results showed no statistical significance in the number of fibroblasts between different groups. However, dexamethasone groups and the one receiving 500 mg/kg of extract differed significantly from the control group in terms of inflammation and bleeding. Furthermore, the number of fibrocytes in the groups receiving 500 mg/kg and 250 mg/kg doses of Viola odorata and Pistacia atlantica extracts was significantly different from the control and dexamethasone groups (P <0.05).Recommended applications/industries: According to the results, the amount of collagen and fibrocytes in the group treated with 500 mg/kg had a significant difference, compared to other groups, probably due to the anti-inflammatory, antibacterial and antioxidant properties of Viola odorata and Pistacia atlantica. They can be used in traditional medicine along with other medicines. Manuscript profile -

We evaluated the 6 months chronic exposure effects of its ethanol leaf extract in Wistar rat.Experimental: A total of 48 rats were randomized into four groups of 12 each as follows; group A (control) and the test groups B-D received 31.25, 62.5 and 125 mg/kg of the leaf extract, respectively. Blood samples were collected via retro-orbital puncture for baseline determination of haematological and biochemical parameters. Thereafter, rats were dosed orally (p.o) for 180 days (6 months) and blood samples were collected for the determination of haematological, biochemical parameters on the 181st day. Liver and kidneys were harvested for histopathology analyses. A 28 - day recovery study was also conducted to determine reversibility in toxicological effects.Results: There was no significant alteration (P>0.05) in heamatological, lipid profile and electrolyte parameters as well as body weight gain and relative organ weights of animals that were exposed to the extract when compared with control group. However, there was significant (P<0.005) reductions in alanine aminotransferase (ALT) and aspartate aminotransferase (AST) as well as elevation in urea and creatinine levels of extract treated groups. Histological sections did not reveal toxicity of liver architecture on day 181st, except dose dependent kidney toxicity, which was reversed following the recovery study.Recommended applications/industries: The leaf extract of Dryopteris filix-mas may be nephrotoxic following 6 months exposure.
