A Case of Unilateral Female Reproductive Organs in Ascaris lumbricoides

The female reproductive organs of Ascaris lumbricoides represented one fifth of the total fresh weight and contained two thirds of the total body lipids. These lipids consisted of saponifiables (79%) and unsaponifiables (21%). Phospholipids of the lecithin–cephalin type were present, as well as an abundance of triglycerides. The latter contained unusually large amounts of C2—C0 saturated volatile acids among which acetic and hexanoic acids predominated. Ascaryl alcohol was the major constituent of the large unsaponifiable fraction, and on the basis of previous chemical analyses and of infrared spectra a hypothetical structure is proposed. A sterol mixture containing significant proportions of both saturated and unsaturated components was also isolated, but not identified further.

High Metabolic Activity

The ultrastructure of reproductive organs of pine, spruce, larch and ginkgo was investigated. It was found that the male reproductive organs possess similar organization. The most considerable change in the ultrastructure of the microsporocytes occur in meiosis. Sporoderm is being laid at the late tetrad stage. The cells of the male gameto-phyte are distinguished according to the metabolic activity of the or- ganells. They are most weakly developed in the spermiogenic cell. Ta-petum of the gymnosperms is of the periplasmodic - secretorial type. The Ubisch bodies which possess similar structure in the types investigated but are specific in details in different species are produced in tapetum.Parietal and subepidermal layers are distinguished for their high metabolic activity and are capable of the autonomous photosynthesis. Female reproductive organs differ more greatly in their struture and have the most complicated structure in primitive groups. On the first stages of their formation the inner cells of nucellus are transformed into the nucellar tapetum in which the structures similar to the Ubisch bodies taking part in the formation of the sporoderm of female gametophyte have been found.

Female Reproductive Organs

Implicit, underlying imagery in medical descriptions of menstruation and menopause is exposed, beginning with 19th century views. Contemporary medical texts and teaching reveal two fundamental assumptions about women's bodies. First, they assume that female reproductive organs are organized as if they form a hierarchical, bureaucratic organization under centralized control. Given this assumption, menopause comes to be described negatively, as a process involving breakdown of central control. Second, they assume that women's bodies are predominantly for the purpose of production of desirable substances, primarily babies. Given this assumption, menstruation comes to be seen negatively, as a process involving failed production, waste products, and debris. Alternative imagery that works from our current understanding of physiology, but avoids denigration of women's bodies, is suggested.

Female Reproductive Organs

The female reproductive organs (ovary, vitellaria, and Mehlis' gland) of the digenetic trematode Halipegus eccentricus were studied by transmission electron microscopy. Oocytes entered diplotene while in the ovary and produced cortical granules and lipid bodies. Vitelline cells produced large amounts of eggshell protein but no yolk bodies. Two types of Mehlis' gland secretory cells were present, distinguishable by the morphology of their rough endoplasmic reticulum, Golgi bodies, and secretory bodies, and by the persistence of recognizable secretory material within the ootype lumen after exocytosis. In an attempt to standardize the nomenclature regarding the cell types of the Mehlis' gland, a classification that takes into account these four criteria is proposed. Two basic types of Golgi body organization were noted for the cells of the female reproductive system: a stack of flattened cisternae (Mehlis' gland alpha cells) and spherical Golgi bodies with vesicular cisternae (oocytes, vitelline cells, and Mehlis' gland beta cells).
