The leaves and seeds of Aframomum alboviolaceum and Aframomum angustifolium are specifically used by traditional healers in the Democratic Republic of Congo (DRC) for the treatment of several pathologies. The aim of present study was to determine the microscopic characteristics and phytochemical composition of these species of the genus Aframomum. The microscopic study of these plants revealed the presence of punctate vessels, fiber cluster with calcium oxalate crystals, isolated unicellular hair, fibers, starch grains, spiral vessel fragments, fiber fragments, and indistinct parenchyma fragments. Phytochemical screening revealed several chemical groups such as phenolic acids, flavonoids, coumarins, alkaloids, terpenes, iridoids, saponins etc. The determination of total polyphenols, flavonoids and tannins gave contents ranging from 14.95 ± 0.45 and 63.98 ± 2.04 mgGAE/g, 0.16 ± 0.01 and 10.68 ± 0.32 mgQE/g and between 1.28 ± 0.03 and 28.51 ± 0.56 mg CAE/g respectively. In general, the leaves are richer in secondary metabolites, polyphenols, flavonoids and tannin than the seeds. Both plants also contain iron, magnesium, calcium and sodium. To our knowledge, this is the first time that histological elements have been identified in the leaves and seeds of A. angustifolium.

The present study was designed to evaluate the Phytochemical Screening for Analgesic and Anti- inflammatory activities of Ethonolic extract of Saussurea lappa.  The collected plant root material were washed, shade dried, and size reduced into small pieces. Dried materials were coarsely powdered and macerated with petroleum ether for 72 hrs. The plant material was extracted by using ethanol by the cold maceration method. The study concluded that the root extract have potential bioactive substances that may be used to formulate new drugs. The Flavo-Glycosides content in Ethonolic extract of Saussurea lappa root was extracted and results were compared with the standard for Analgesic and Anti- inflammatory activities. The results were compared with the standard using statistical method. However further investigation was required for structural elucidation and pharmacological properties. Keywords: Saussurea lappa, Ethonolic, Glycosides, Analgesic, Anti-inflammatory.

Genetically uniform shoots of Eryngium alpinum L. cultured in vitro were subjected to the qualitative analysis applying the UPLC-HESI-HRMS technique. In vitro cultures give the opportunity to perform the phytochemical studies on the protected species without harvesting the plant material from the natural environment. The phytochemical screening of the crude methanolic extracts of shoots, both from in vitro cultures and in vivo plants, revealed the presence of phenolic acids, coumarins, flavonoids, triterpenoid saponins, amino acids, or dipeptides. Active compounds detected are known to have medicinal importance, and for this reason, the present study represents a preliminary investigation of the extracts against pathogenic and opportunistic amoeba. Among the extracts tested, the extract of shoots from in vitro cultures exhibited remarkable amoebicidal action against trophozoites. On the second day of treatment, the extract at the concentrations of 5 mg/mL, 2.5 mg/mL, and 0.5 mg/mL showed the highest antiamoebicidal effect: the inhibition of trophozoites reached 81.14%, 66.38%, and 54.99%, respectively. To our best knowledge, the present report is the first to show the phytochemical screening and to discuss the antiamoebic activity of Eryngium alpinum L. shoots, both from in vitro cultures and in vivo plants.

The phytochemical screening of Terminalia avicennoids was carried out using qualitative method to determine the bioactive compounds present in the plant root, stem and leave extracts. Cooled Maceration method was used for the extraction.  Hundred grams (100 g) of each powder was soaked in 1000 ml of distilled water, allowed to stand for 5 hours.  The suspension was agitated after 30 minutes. The filtrate was thereafter separated from residue using No. 1 Whatman filter paper and concentrated using rotary evaporator. The crude extracts were separately kept in a screw capped bottle for further research. The bioactive compound in the plants were detected using AOAC method. The result revealed that alkaloid, flavonoid, tannin, saponins, phenol and glycoside were detected in the plants while steroid was not detected in the plants. Therefore, the presence of these phytocompounds is an indicative that the plant is medicinal and it can be used for the treatment of bacterial and fungal infections.

The synthetic androgen danazol, is an isoxazol derivative of ethisterone. It is utilized in the treatment of endometriosis, fibrocystic breast disease, and has a potential use as a contraceptive. A study was designed to evaluate the ultrastructural changes associated with danazol therapy in a rat model. The preliminary investigation of the distal segment of the rat uterine horn was undertaken as part of a larger study intended to elucidate the effects of danazol on the female reproductive tract.Cross-sections (2-3 mm in length) of the distal segment of the uterine horn from sixteen Sprague-Dawley rats were prepared for SEM. Ten rats in estrus served as controls and six danazol treated rats were noted to have alterations of the estrus cycle i.e. a lag in cycle phase or noncycling patterns. Specimens were fixed in 3% glutaraldehyde in 0.05M phosphate buffer containing CaCl2 at pH 7.0-7.4 and chilled to 4°C. After a brief wash in distilled water, specimens were passed through a graded series of ethanol, critical point dryed in CO2 from absolute ethanol, and coated with 6nm Au. Observations were made with an IS1-40 SEM operated at 15kV.

Preliminary investigation has indicated similarity in hepatic ultrastructural morphology in nutritional deprivation, and cyanide induced hepatic necrosis. Analysis of hepatic tissue has indicated disruption of intracellular membranes, specifically, reduction in rough endoplasmic reticulum (RER) mitochondrial integrity, and glycogen stores. An increase in smooth endoplasmic reticulum (SER) portion was observed.To further investigate the apparent equivalence of necrotic morphology, ultrastructura1ly, BDF1 mice were subjected to senescence, nutritional deprevation, potassium cyanide (KCN) induced toxemia, and acetaminophen induced toxemia. Controls were utilized to ellucidate non-necrotic hepatocellular normals. U1trastructura1 investigation of controls (Fig. 1) shows densely granular RER, abundant glycogen stores, and morphologically normal mitochondria. Subjects with acetaminophen induced necrosis exhibit reduced normal RER with increased levels of dialated, vesicular RER in apparent conversion to SER (Fig. 2), loss of mitochondrial integrity, and glycogen store reduction. Senescent subjects exhibit a pronounced increase in SER and loss of glycogen store. (Fig. 3). Investigation of the senescent SER at high magnification (Fig. 5) indicates that the SER is arising from degranulating and vesiculating RER.

KeponeR (decachlorooctahydro-1,3,4-metheno-2H-cyclobuta[cd]pentalen-2-one) is an insecticide effective against ants and roaches. It can cause severe toxicity in fishes, birds, rodents and man. Prominent effects include hepatic lipid deposition and hypertrophy, impairment of reproductive capacity and neurological disorders. Mitochondrial oligomycin-sensitive Mg2+-ATPase is also inhibited. The present study is a preliminary investigation of tissue ultrastructural changes accompanying physiological signs of acute toxicity, which after two days treatment include: pronounced hypersensitivity and tremor, various degrees of anorexia and adipsia, and decreased weight gain.Three different series of adult male Sprague-Dawley rats (Charles River or CD-I) were treated by intubation with Kepone in corn oil at a dose of 50 mg per kg for 3 successive days or at 200 ppm in food for 8 days. After ether anesthesia, rats were immediately perfused via a cannula in the left ventricle with 4% p-formaldehyde and 0.5% glutaraldehyde in Millonig's phosphate buffer at pH 7.2 for 20-30 min at 22°C.

Chromophobe pituitary adenomas arise from adenohypophysial cells and fail to exhibit cytoplasmic staining with conventional acid or basic dyes by light microscopy. The aim of the present work was to study the electron microscopic features of these tumors, to separate them into distinct entities and to correlate their fine structural appearances with secretory activity.Among 48 surgically removed various pituitary adenomas 30 tumors were found which, based on the tinctorial characteristics of the cytoplasm, corresponded to chromophobe adenomas. For electron microscopic investigation pieces of these tumors were fixed in 2.5 per cent glutaraldehyde in Sorensen's buffer, post fixed in 1 per cent osmium tetroxide in Millonig's buffer, dehydrated in graded ethanol and embedded in Epon 812. Ultrathin sections were stained with uranyl acetate and lead citrate.By electron microscopy it was possible to separate chromophobe adenomas into 3 distinct entities: 1) adenomas consisting of sparsely granulated growth hormone cells (7 cases).
