Bone marrow-derived cell (BMDC) therapy has numerous applications as potential biological cells for use in regenerative medicine. Here, we present an original case of endometrial atrophy associated with genital tuberculosis in a woman who achieved a live birth with BMDC. This 27-year-old woman came to our center with endometrial atrophy and primary infertility. She had a past history of genital tuberculosis and amenorrhea. Her husband's semen quality was normal. The patient was counseled for hysteroscopy due to thin endometrium and advised in vitro fertilization (IVF) with donor eggs in lieu of poor ovarian reserve. Several attempts of IVF with hormone replacement therapy (HRT) were made, but the desired thickness of the endometrium was not achieved. Uterine artery injection of BMDC through interventional radiology was given, followed by HRT for three months, which resulted in improved endometrium. This was subsequently followed by IVF with donor egg. The treatment resulted in the conception and delivery of a 3.1-kg baby boy through lower segment caesarean section with no antenatal, intranatal or postnatal complications. Recently, there has been massive interest in stem cells as a novel treatment method for regenerative medicine, and more specifically for the regeneration of human endometrium disorders like Asherman syndrome and thin endometrium, which was the reason behind using this strategy for treatment.

Two species of the minuta-subgroup within the oncaeid copepod genus Triconia $B{\ddot{o}}ttger$-Schnack, 1999 collected in the equatorial Pacific Ocean are newly recorded. A female T. minuta (Giesbrecht, 1893 ["1892"]) and both male and female T. umerus ($B{\ddot{o}}ttger$-Schnack and Boxshall, 1990) from the northeast equatorial Pacific are redescribed with the comparison of its morphological details, which differs from previous studies, in terms of the larger body size, the length to width ratio of the genital double-somite, the relative length of the outer basal seta on P5, and the ornamentation of the appendages. The characters, which are used for identification, such as the length ratio of the outer subdistal and outer spine versus the distal spine on P3-P4, and the outer spine length of the middle exopodal segment on P3 and P4 are reported for the first time. Information on the variations in the endopodal spine lengths of swimming legs 2-4 is also provided for T. minuta and T. umerus, with the summary of the wide zoogeographical distribution of these two species.

Acanthochondria spirigera is redescribed based on the specimens recovered from the Lophiomus setigerus in the southern coast of Korea. This parasitic copepoda is distinguished from congeners by the possession of spirally twisted egg-strings. Acanthochondria spirigera(Chondracanthidae, Poecilostomatoida) is the first recorded species from Korea. This parasitic copepod was not found on the fish in May. Relative density and prevalence also decreased from January to May. A. spirigera live symbiotically within the pharyngeal cavity of the L. setigerus, and eat oesophageal mucous string of their hosts. The male of the parasitic copepoda is dwarf, and found on the ventral surface of genital segment of the female.

Physiological and morphological differences in larvae and female adults of Thecodiplosis Japonensis from Haenam, Chullanamdo, and Chunsung, Kangweondo, were studied by means of electrophoretic technique and scanning electron microscope (SEM). On zymograms of whole body, third instar larvae of T. japonensis showed geographic differences in the band patterns of esterase and MDH iszymes, but patterns and the staining density of general proteins were similar in tow populations. In female adults, the populations revealed geographic differences in general proteins and esterase isozymens. In external ultrastructures, especially in genital segments, each population had distinctive structures in the 2nd segment of ovipositor.

Parasitism of Pseudocaligus sp. in wild grass puffer Takifugu niphobles in the coast of Yeosu in spring, 2007 was identified. The preadult and adult stages of Pseudocaligus sp. were observed, which consisted of cephalothorax, genital segment and abdomen. Lunules were present on the anterior margin of the frontal plate. In order to develop the treatment method, we examined the effects of formalin and fresh water on the parasite. The Pseudocaligus sp. were detached from the host fish by bathing at concentrations of 50 to 400 ppm formalin within 60 min, but 57% was exterminated to fresh water for 90 min.

SEM and LM studies were made to examine the frustule of the marine epizoic diatom Pseudohimantidium pacificum Hustedt & Krasske and to examine the variability of frustule morphology. The length of the apical axis and the transapical axis were similar to other reports. but Number of labiate processes showed a variation. the Number of striae of Korean specimens were similar to those of other regions, but the areolae shape of striae showed elliptical type. Pseudohimantidium pacificum were palnktonic, tychopelagic or epizoic attached to the prosome, the genital segment and abdomen of corycaeus affinis. this species was newly recorded I Korean waters and the biogeographic boundary of this species can therefore be extended to the northern Pacific Ocean.
