The changes in the size of human oviduct and ovary after immersion in formalin (4%, 10%) were investigated. The results were as follows : 1. After fixation, the length of oviduct was significantly reduced to 93%, but the cross sectional area of oviduct was significantly increased. The length of oviduct showed no significant difference between 4% and 10% formalin. The length of ovarian ligament was also significantly reduced to 84% after fixation. 2. After fixation, the volume of oviduct was increased significantly and showed a difference between the two fixatives. The volume of oviduct in 4% formalin has increased to 107%, as compared to 103% increase in 10% formalin. 3. After fixation, the volume of ovary was increased significantly and showed a difference between the two fixatives. The volume of ovary in 4% formalin has increased to 109%, as compared to 103% increase in 10% formalin.

Page 31. The size of conidia of Alternatia brassicicola should be 20~80x8~25 microm instead of 20~120x8~30 microm.

The taxonomy of the Alternaria spp. has been a subject, of controversy because of their high variability in conidial morphology and polymorphism displayed even in pure cultures. The published Korean literature on the genus Alternaria is scattered and fragmentary, and pertains to about 25 species with special emphasis on occurrence and pathogenicity, but mycological studies on this group of fungi are insufficient. This is the first series of detailed and consolidated account of Korean species of Alternaria, which includes 11 species; viz., Alternaria brassicae, A. brassicicola, A. cinerariae, A. dauci, A. dianthi, A. dianthicola, A. helianthi, A. helianthinffciens, A. iridicola, A. japonica and A. protenta. Detailed diagnostic descriptions, specific characterizations, taxonomic discussions and illustrations for each species are presented.

Congenital absence of inferior vena cava is an uncommon abnormality. With advent of modern imaging techniques such cases are being found with increasing frequency. I report the case of an otherwise healthy 44-year-old man with severe venous insufficiency involving both lower extremities manifested by multiple ulcerations. This condition was caused by a combination of congenital and acquired factors. Ulcerations were managed successfully with aggressive conservative treatment.

Hereditary peripheral neuropathies can be categorized as hereditary motor and sensory neuropathies (HMSN), hereditary motor neuropathies (HMN), and hereditary sensory neuropathies (HSN). HMSN, HMN, and HSN are further subdivided into several subtypes. Here, we review the most recent findings in the molecular diagnosis and therapeutic strategy for hereditary peripheral neuropathies. The products of genes associated with hereditary peripheral neuropathy phenotypes are important for neuronal structure maintenance, axonal transport, nerve signal transduction, and functions related to the cellular integrity. Identifying the molecular basis of hereditary peripheral neuropathy and studying the relevant genes and their functions is important to understand the pathophysiological mechanisms of these neurodegenerative disorders, as well as the processes involved in the normal development and function of the peripheral nervous system. These advances and the better understanding of the pathogenesis of peripheral neuropathies represent a challenge for the diagnoses and managements of hereditary peripheral neuropathy patients in developing future supportive and curative therapies.

PURPOSE: To evaluate the MR findings of embolized cerebral arteriovenous malformations according to various embolic materials. MATERIALS AND METHODS: We performed the endovascular embolization using four different kinds of embolic materials in 33 patients. Embolization related changes in the nidus and surrounding brain parenchyme were analyzed and the results were compared with pre- and postembolization MRI, CT and anglographic findings in all patients. RESULTS: Embolized vessels with N-buthyl-2-cyanoacrylate(NBCA) mixture showed some artifact in CT due to metallic character of tantalum powder or fatty nature of lipiodol. But in MRI, it was represented by fatty signals without artifact. In cases of using polyvinyl alcohol and ethylene vinyl alcohol copolymer(EVAL), there were no specific signal by the embolic material except for the disappearance of flow related signals in feeding arteries and shrinkage of venous ectasis. CONCLUSION: MRI is a valuable imaging modality for analysing the morphology and hemodynamics of cerebral AVMs, especially after embolization of pathologic vessels. Recognition of the signal of embolic agents and thus the thrombosed portion could lead to more precise analysis before surgery or radiosurgery.
