Carnitine deficiency.

We present the case of a female patient, aged 12 years, with fatigability and exertional myalgias, progressively developed within the last two years. Negative family history, as well as negative personal medical history, were found. At physical examination, short stature, proximal muscle weakness and mild hepatomegaly were noted.

Comparative microscopic study of the ovarian blood vessels.

The present study puts forth the morphometric analysis of modifications that occur in the ovarian structures (stroma, parenchyma, blood vessels) before and after menopause onset. Our study was performed on 30 human ovary specimens from patients with no history of genital pathology that were split in two groups (15 ovaries harvested from fertile women and 15 ovaries harvested from women at menopause). The specimens were processed following the classic histological technique of paraffin embedding and stained using Hematoxylin-Eosin technique and trichromic Goldner-Szeckelly technique.

Cerebellar atrophy--a comparative microscopic study.

The cerebellum is required for the coordination of fine movement. In health, it provides corrections during motion which are the basis for precision and accuracy, and it is critically involved in motor learning and reflex modification. Disease of the cerebellum or its connections leads to incoordination.

Correlated histological and morphometric study of kidney and adrenal gland from Guinea pig exposed to hyperbaric-hyperoxic environment.

Our study revealed morphological changes in the two organs of Guinea pig kidney and suprarenal gland exposed to hyperbaric-hyperoxic environment. Proceeding from these data and knowing that in hyperbaric-hyperoxic environment the production of free oxygen radicals is increased, while the afferent arterioles undergo vasoconstriction, with direct implications on the cellular metabolism, our study puts forth the survey of the influence of hyperoxic environment on kidneys and adrenal gland - complex organs which are exposed to stress.

Aspects of the cell population in the skin of the guinea pig exposed to hyperbaric-hyperoxic environment.

Knowing that in hyperbaric-hyperoxic environment, the production of free oxygen radicals is increased, with the direct implications on cellular metabolism, our study follows the influence of the hyperbaric environment, a very complex organ that is exposed to directly to this environment. We used a group of 10 guinea pigs split into to lots (test and control lots). The test lot was exposed for consecutive days to an ambient pressure of 6 ATM for a period of 30 min.
