[Expression of LIF gene during early development of mouse embryo]
[Article in Chinese]

Leukemia inhibitory factor (LIF) has the ability to maintain the development potential of pluripotent embryonic stem cells, suggesting that this factor might play an important role during mouse embryogenesis. By whole mount in situ hybridization on early mouse embryos, we have examined the expression pattern of the LIF gene from the two cell stage to the preimplantation blastocyst with the following results. (1) LIF transcripts were detected at all stages before implantation, but the highest level of LIF mRNA expression occurred in the blastocyst stage. (2) For the cleavage stages of mouse embryo, there was no significant distinction of the LIF gene expression level between blastomeres, but a strong signal was detectable in the cells which surrounded the blastocoel cavity of the blastocyst and most of them belonged to future extraembryonic tissues. These results suggest that a principal function of LIF in vivo may be to regulate stem cell population and to play an important role in the implantation of the blastocyst.

[Expression of retinoic acid receptor gamma gene in ES cells and its effect on their differentiation and apoptosis]
[Article in Chinese]

We have constructed pSG5-RAR gamma-neo plasmid containing mouse retinoic acid receptor gamma (RAR gamma) gene and neo gene, and introduced it into embryonic stem ES-5 cells, by calcium phosphate mediated transfection. Some G418-resistant clones were isolated and from RNA dot blot analysis of these clones, a clone overexpressing RAR gamma gene was established, designated as ES-gamma cell line. Northern blot hydridization and Southern blot hydridization analysis of ES-gamma cells (Fig 3, 4) demonstrated that ES-gamma cells overexpressed exogenous RAR gamma mRNA and the exogenous RAR gamma cDNA integrated into the genome of ES cells. ES-gamma cells retained undifferentiated morphology and positive alkaline phosphatase activity (Plate I, Fig. 1, 2), so it resembled ES-5 cells in terms of stem cell characteristics. When ES-gamma cells were subcutaneously inoculated into nude mouse and differentiated in vivo, tumorous nodules containing various tissue structures were obtained, demonstrating their pluripotent properties just like parent ES-5 cells. Contrasting with ES-5 cells, the histological features of tumors showed no cartilage tissues, but abundant muscle tissues and keratinized cyst like structures constituted by stratified squamous epithelia (Plate I, Fig. 3). Differentiating in vitro by hanging drop culture methods, ES-gamma cells differentiated mostly into fibroblast-like cells, (Plate II, Fig. 1-5). The above results indicated that overexpression of RAR gamma gene changed the cell type of ES cells differentiating in vivo and in vitro. During the differentiation of ES-5 cells induced by RA, a large number of cells rounded up, detached from the dish and tended to die. We suspected that this phenomenon may be apoptosis. The ultrastructure appearance of the dying cells displayed typical apoptotic changes including chromatin condensation and nuclear fragmentation (Plate I, Fig. 4, 5). Detection of DNA fragments using agarose gel electrophoresis showed characteristic laddered patterns of apoptotic DNA fragments (Fig. 5). The above results indicated that RA induced apoptosis of ES-5 cells in the course of differentiation. The percentage of apoptosis of ES-5 cells increased accordingly, with the increase of RA concentration (Fig. 6). With the same concentration of RA 10(-7) mol/L, the percentage of apoptotic of ES-gamma death was roughly one times more than that of ES-5 cells (Fig. 7), a fact indicating that RAR gamma may mediate the apoptotic signal transduction of ES cells by RA.

BACKGROUND: The quality of sexuality is significantly affected by physical changes following hematopoietic stem cell transplantation (HSCT) and the dissatisfied and/or dysfunctional sexuality may cause deterioration in the quality of life (QOL). METHODS: With two models of questionnaires, we interviewed thirty-eight patients who remained in the disease-free status after HSCT and had sex partners, to assess: 1) the changes in sexuality, 2) QOL in physical, psychological, social and spiritual domains and 3) the correlation between sexuality and QOL. RESULTS: The common physical changes that may affect sexuality in women were secondary amenorrhea (69.2%), loss of sexual interest (53.8%), diminished vaginal secretion (50%), menopausal syndrome (34.6%), dyspareunia (30.8%) and failure to orgasm (23.1%), while men complained of impotence (41.7%) and difficulty in ejaculation (16.7%). For sexuality, satisfaction of sexual activity, attainment of orgasm and frequency of intercourse decreased significantly after HSCT as compared with the pre-transplant levels. A score measuring, QOL after HSCT marked 5.91 on a full score of 10; social domain ranked the lowest (5.01) while physical domain the highest (6.70). Among the items of sexuality, only sexual desire was significantly correlated with QOL; satisfaction, orgasm and frequency were not significantly correlated with QOL. CONCLUSION: Although sexuality is affected by the physical changes following HSCT, we should not overlook the psychological and social effects on the sexuality of post-transplant patients. Therefore, educational and counseling programs are very important to restore and improve their sexuality.

Providing a cure for beta thalassaemia major.
Chan LL, Lin HP, Ariffn WA, Ariffin H.
Department of Paediatrics, Faculty of Medicine, University of Malaya, Lembah Pantai, Kuala Lumpur.
The current treatment options for beta thalassaemia major patients include conservative treatment with blood cell transfusions and iron chelation or stem cell transplantation. Regular blood transfusions inevitably lead to multi-organ haemosiderosis and are attended by risks of blood-borne infections. Results from stem cell transplantation are good and suggest that this should be offered as first line therapy when a matched sibling donor is available because the patient is often cured and able to live a normal life. Of 38 Malaysian children who underwent bone marrow or cord blood transplantations using matched sibling donors, 29 (76%) are now cured.

Fatal haemophagocytic syndrome.
Fadilah SA, Raymond AA, Cheong SK, Amir MA.
Division of Clinical Haematology and Stem Cell Transplantation, Faculty of Medicine, Universiti Kebangsaan Malaysia, Kuala Lumpur.
A fulminant clinical presentation with high fever and hepatosplenomegaly, together with a course of worsening pancytopenia, coagulopathy and liver failure, is suggestive of the haem syndrome (HPS). Bone marrow examination is diagnostic. We present 3 cases of HPS associated with different aetiologies including acute Ebstein Barr virus infection, T cell lymphoma, and malignant histiocytosis. In all the cases, the diagnosis was made late and the patients succumbed before definitive therapy could be administered.

Hair loss is a problem in modern soceity. Examining the factors of hair growth may
shed light on how hair loss might occur.
How long can hair grow before it stops growing eventually if it does?
Given that the hair growth rate is quite uniform and constant, somewhere between 0.3-0.5 millimeters per day, it's believed that the length of anagen, the growth phase, differs among individuals, and this is the major determinant to the maximum hair length. For some individuals, anagen may last ten years. Of course the length of the anagen is governed by genes, and the genetic background of the individuals. Non-genetic factors such as nutritional condition, weather, seasonal changes (hair may grow a bit faster during winter), taking medications, health condition may of course influence the rate of
hair growth as well as
hair loss.
The shape of the hair, straight or curly, is dependent on the shape of the follicle. A circular or round hair follicle would generate straight hair, while the follicle with oval or elliptical shapes (in its cross-section) would produce a curly hair.
DHEA is a natural hormone, and it is produced in our body by the adrenal glands.
DHEA has been suggested to provide numerous potential benefits. DHEA (or dehydroepiandrosterone) is converted into androgens (male hormones)
or estrogens (female hormones) in the cells.
