Surface ultrastructure of Parvatrema timondavidi developmental stages was studied using a scanning electron microscope. The metacercariae were collected from the marine clam, Tapes philippinarum, and juvenile and worms adult were recovered at 1, 2, 3, and 7 days after experimental infection of mice. The metacercariae had a large oral sucker and characteristic lateral projections. Around the lip of the oral sucker many type I and type II sensory papillae were observed, and type III papillae were located symmetrically on the medial side of the lateral projection. Numerous type I papillae were grouped around the genital pore. The tegumental spines were distributed over the worm surface except the lip of the sucker and genital pore. The 1-day old worm had a well-developed ventral sucker, with 6 type II sensory papillae on its outer surface and another 6 type I papillae on the inner side, Two small type I papillae were seen on the anterior side of the ventral sucker. The genital pore was and 15 type I papillae were grouped around it. The 2-, 3-, and 7-day worms revealed that as they grew to be adults, the spine tips became multipointed, the genital pore formed a genital atrium, and the cytoplasmic process became well differentiated. In 2- and 3-day worms 10 type II papillae encircling the lip of the oral sucker, and additional 4 papilled at the dorsal side of 4 dorsal type II papillae were a characteristic feature. The distribution pattern of sensory papillae around the oral sucker and genital pore, and 2 type I papillae on the anterior side of the ventra sucker, was so peculiar in P. timondavidi, that they seem to be useful keys for taxonomic differentiation from other gymnophallids.

OBJECTIVE: Pituitary adenylate cyclase-activating polypeptide (PACAP), a novel hypothalamic neuropeptide, has been suggested to play a role in ovarian folliculogenesis. The present study evaluated the effect of PACAP on the growth of preantral follicles. METHODS: Preantral follicles were mechanically isolated from ovaries of 21-day-old rats and cultured in groups for 3 days in serum-free medium in the absence or presence of PACAP-38 (10-6 M). RESULTS: Treatment with PACAP-38 resulted in an increase in follicle diameter by 75% whereas treatment with follicle stimulating hormone (FSH) increased follicle diameter by 65%. PACAP-38 treatment enhanced the granulosa cell proliferation as measured by thymidine incorporation analysis. Furthermore, the production of progesterone by cultured granulosa cells and GFSHR-17 cell line was stimulated by PACAP-38. Interestingly, PACAP enhanced FSH action on stimulation of SF-1 and aromatase gene expression. CONCLUSION: The present results demonstrate that PACAP stimulated preantral follicle growth by potentiating proliferation and by stimulating steroidogenesis.

5.Cryotherapy for retinopathy of incontinentia pigmenti.
Korean Journal of Ophthalmology 1991;5(1):47-50
A case with typical skin lesions of incontinentia pigmeti showed progressing retinal vascular abnormalities. So cryotherapy was done on avascular peripheral retina, and retinal vascular changes ceased. We propose that cryotherapy may be a good treatment method for progressing retinal vascular lesions of incontinentia pigmenti.

DNA profiling with sets of short tandem repeat (STR) markers is the most popular method for identifying human DNA in forensics. Identification by STR typing might fail when DNA is degraded or is present in low amounts, such as in disaster victim identification (DVI) samples. In such cases, more information might be obtained by using additional markers such as single nucleotide polymorphisms (SNPs). Multiplex PCR and microarray are convenient techniques to analyze SNP markers. We used an AccuID(TM) Chip, SNP-based DNA chip manufactured by DNA Link Corporation, to confirm genetic relationship between two human bone samples that had been buried for more than 50 years and blood samples from the alleged descendants of the sources of the bone fragments. The chip combines an Affymetrix resequencing array with a multiplex PCR technology and can genotype hundreds of SNP markers in a single experiment. Genotyping the two bone samples yielded 90.5 and 77 SNP markers. The commonly genotyped markers (61 and 47 SNP loci) in each bone-family pair provided high paternity indices to support the genetic relationships in both cases.

OBJECTIVES: Bok, Bcl-2-related ovarian killer, is a proapoptotic Bcl-2 family protein identified in the ovary based on its dimerization with the antiapoptotic protein Mcl-1. The present study examined the hormonal regulation and localization of Bok messenger RNA levels in the mouse ovary during the follicle development. METHODS: The animals were implanted subcutaneously with Silastic brand capsules containing the synthetic estrogen, DES at 21~23 days of age. Ovaries were collected 1~3 days after implantation for RNA analysis and in situ hybridization. Some mice were removed capsule for 1~2 days to induce ovarian follicle apoptosis. Ovaries were also collected from 26 day-old immature mice at various times after treatment with 10 iU PMSG. Some mice received a single intraperitoneal injection of 10 iU hCG to induce ovulation, and ovaries were obtained at different time intervals for Northern blot and in situ hybridization analysis, respectively. RESULTS: Treatment of immature mice with diethylstilbestrol (DES) for 24~48 h increased ovarian Bok mRNA levels. Bok mRNA was remained the same levels in mice removed DES for 24~48 h to induce apoptosis. High signals of Bok mRNA after DES treatment were detected in granulosa cells of early antral follicles. Treatment of immature mice with PMSG for 12 h increased markedly ovarian Bok mRNA expression which was detected mainly in preantral and atretic follicles. interestingly, low levels of Bok mRNA were also expressed in granulosa cells of preovulatory follicles. Treatment of PMSGprimed mice with hCG stimulated strongly ovarian Bok mRNA expression at 6~9 h. At that time, Bok mRNA was expressed in granulosa cells of atretic and small growing follicles. CONCLUSION: These results demonstrate that Bok is one of proapoptotic Bcl-2 members expressed in early growing and atretic follicles during the ovarian follicular development. Gonadotropins induce a transient increase of Bok gene expression in granulosa cells of preantral and preovulatory follicles indicating some role in the ovulatory process.

Korean Circulation Journal 2009;39(11):482-487
BACKGROUND AND OBJECTIVES: This study was aimed at evaluating the significance of blood pressure (BP) load in ambulatory blood pressure monitoring (ABPM) in obese children and adolescents. SUBJECTS AND METHODS: ABPM was conducted for 60 selected patients who had visited Sunlin Hospital between January 2008 and August 2008. Patients were classified into 3 groups; an obese group whose body mass index (BMI) was > the 95th percentile, an overweight group whose BMI was > the 85th percentile but less than the 95th percentile, and a normal group whose BMI was below the 85th percentile. Overall mean BP, day and night BP and BP load were measured by ABPM. RESULTS: Of the 60 patients, twenty-seven children belonged to the obese group, 9 and 24 to the overweight and the normal group, respectively. Among the three groups, the overall average systolic and diastolic BP, daytime diastolic BP, and systolic BP loads in daytime and nighttime were statistically different. Comparing the obese group with the normal group, systolic BP loads in daytime and nighttime in the obese group were significantly higher than those in the normal group. Also, the obese group had more patients whose BP loads were over 25% greater than the normal group while the difference in the number of patients with overall hypertension was not significantly different. CONCLUSION: Assessment of children's BP through assessment of BP load is a more detailed and precise tool than assessment through mean BP using ABPM and BP can be better controlled using measurement of BP load.

The Dandy-Wlaker syndrome is a developmental disoeder characterized by cystic dilatation of the fourth ventricle and agenesis or hypoplasia of the cerebellar vermis and is usually associated with hydrocephalus. This syndrome is also associated with intracranial malformations such as agenesis of corpus callosum, and extracranial malformations such as facial anormalies (cleft palate, cleft lip, and ocular anomalies), polycystic kidney, and cardiac anormalies. Reported associated ophthalmic anomalies are microphthalmos, coloboma, and congenital cataract.We experienced a case of infantile esotropia in abnormal insertion and direction of lateral rectus muscle as a variant of the Dandy-Walker syndrome accompanied by cleft palate and cleft lip in a 19-month-old male infant. Subsequent treatment of the 30delta esodeviation and left inferior oblique muscle overaction, including resection of the lateral rectus muscle in both eyes and the myectomy of the inferior oblique muscle in the left eye, yielded satisfactory results, so we report this case, with a review of the pertinent literature, as the first case of Dandy-Walker syndrome associated with esotropia with abnormal course of lateral rectus muscle in Korea.

Aneurysm of the internal carotid artery is a rare disease and is known to be associated with congenital arterial anomalies such as neurofibromatosis type I (NF-I). NF-I is an autosomal dominant neurocutaneous disorder characterized by a variety of manifestations that involve the central and peripheral nervous systems, skin, vascular system, and skeleton. In particular, the involvement of vascular abnormalities in NF-I is well known. Any vessel may be affected by this condition, although the renal artery is most frequently involved. The vascular abnormality can be occlusive or an aneurysmal degenerative change. Therefore, symptomatic presentations might assume an indolent pathophysiologic course such as hypertension, or manifest as a catastrophic event such as arterial rupture that could result in sudden death. We report a rare autopsy case of an aneurysmal rupture of the internal carotid artery in a woman with suspected NF-I, who collapsed in her home.
