Macro-and micromorphology of the leaves, stem bark and flowers of punica granatum L. Var. Nana cultivated in Egypt

Punica granatum L. var. nana [ornamental pomegranate] belongs to family Punicaceae. It is popularly planted in gardens for ornament. The root, stem bark and to a lesser extent fruit rind of the edible pomegranate had been commonly used as a vermifugal or taenicidal agent on tapeworms. By reviewing the literature, no botanical studies were done on Punica grantum L.var. nana, so this study aims for characterization and identification of this plant in both entire and powdered forms

Macro- and micromorphology of the leaves, stems and flowers of Chrysanthemum carinatum L.

The genus Chrysanthemum L. is sometimes called Ismelia, it comprises about 150 species native to tropical and temperate North and South America. Chrysanthemum carinatum L. is known as Painted daisy, German flag and Tricolor Chrysanthemum. Some species of genus Chrysanthemum are used medicinally to cure influenza symptoms, liver and menstrual disorders and have anti-inflammatory and antispasmodic effects

Studies on the teratogenic effects of clindamycin hydrochloride on the ckick embryo

Two doses [7.5 and 15 mg/50 g] of clindamycin hydrochloride were injected into the egg yolk of embryonated eggs of hens on the 5th day of incubation. Consistent effects of clindamycin were embryo lethality [100%], retardation of growth [10.3 to 10.7], ectopic viscera [34.5 to 42%] and a low incidence of anomalies like thin debilitated toes and feet [7 to 10.7%] and alopecia, respectively, [24.1 to 35.7%],. etc. Results suggested that exposure to clindamycin would cause serious reproductive problems in avian species

Sesquiterpene lactones and flavonoids from chrysanthemum vulgare [L.] berth

From chrysanthemum vulgare [L.] Bernh. Three sequiterpene lactones were isolated and identified as 3 beta-hydroxycostunolide [I], 2 alpha, 8 beta-dihydroxycostunolide [II] and tatridin B [III]. In addition, three flavonoids viz. apigenin, luteolin and apigenin-7-0-glucoside were isolated. The structures of these compounds were depicted through spectral studies. All the isolated compounds were reported for the first time from the titled plant

Study of alpha adrenoreceptors and plasma catecholamines in insulin-dependent diabetics

This study was intended to estimate the number and sensitivity of alpha and beta adrenergic receptors in IDDM patients and to determine their relation to plasma catecholamine levels. Plasma epinephrine, norepinephrine and dopamine levels, as well as platelet alpha-2 adrenoreceptor density and responsiveness, alpha-1 receptor sensitivity, B[2] density and responsiveness and B[1] responsiveness were estimated in 43 insulin dependent diabetics and 56 healthy persons taken as control. Plasma norepinephrine levels were significantly low in diabetics, whereas epinephrine and dopamine levels were normal. Platelet alpha-2 receptor density was significantly high and their responsiveness was markedly low in diabetics. Alpha-1 receptor responsiveness was normal. The elevated alpha-2 receptor density could be directly attributed to the low plasma norepinephrine levels. The reduced alpha-2 receptor responsiveness is most probably due to a post-receptor mechanism. This might be beneficial as it partly counteracts the platelet aggregatory effect of the impaired prostacyclin production by the diabetic capillary cndothclium
