RESUMO

Hirsutism is a dermatological condition that refers to the excessive growth of hair in androgen-sensitive areas in women. Recently, the enhancement of the visible signs of a hairy female has taken special concern that affected the quality of life. The present study was developed to compare the follicular targeting effect of topical spironolactone (SP) or progesterone (PG)-loaded nanostructured lipid carrier (NLC) on the management of hirsutism. Four NLC formulations were prepared using cold homogenization techniques and pharmaceutically evaluated. SP-NLC and PG-NLC topical hydrogels were prepared to explore their pharmacological effect on letrozole induced polycystic ovarian syndrome (PCOS) in rats. Inflammatory mediators, antioxidant, and hormonal parameters were assayed. Additionally, histopathological examination was carried out to confirm the successful induction of PCOS. Results confirmed that all NLC formulations have a spherical shape with particle size ranged from 225.92 ± 0.41 to 447.80 ± 0.66 nm, entrapment efficiency > 75%, and zeta potential (- 31.4 to - 36.5 mV). F1 and F3 NLCs were considered as selected formulations for SP and PG, respectively. Female Wistar rats treated with F1 formulation for 3 weeks displayed better outcomes as manifested by the measured parameters as compared to the other tested groups. A significant reduction in hair follicle diameter and density was observed after topical application of SP or PG nano-gels. Finally, the outcomes pose a strong argument that the development of topically administered SP-NLC can be explored as a promising carrier over PG-NLC for more effectual improvement in the visible sign of hirsutism.

RESUMO

This article analyzes how evolving pharmaceutical technology, chemical advances, and world politics created the need for an abundant and cheap supply of steroids, and how decisions made in faraway laboratories ultimately determined that a Mexican yam, barbasco, was the best possible raw material. Following this discovery, this article explores how barbasco's exploitation impacted on the Mexican countryside and specifically the men and women hired to gather wild yams. In analyzing, for example, the peasant organizations that emerged, the use of chemical terms by barely literate peasants, and the Mexican government's political strategy to control rural unrest by controlling barbasco production one begins to understand the unexpected consequences of the global search for medicinal plants. In this particular case, the merging of science and peasant life reshuffled social hierarchies in the countryside, granted monetary value to an erstwhile 'weed', and gave a novel reinterpretation to laboratory knowledge and its (social) uses.

RESUMO

The syntheses of phenylselenium-substituted progesterone [21- (1) and 17 alpha-(phenylseleno)progesterone (2)] and testosterone [16 beta- (3) and 16 alpha-(phenylseleno)testosterone (4)] derivatives are described, along with data which help to establish the stereochemistry of the substituents in the testosterone molecules. Except for 21-(phenylseleno)-progesterone, the molecules exhibit greatly reduced receptor-binding capabilities.
