Abstract
More than 100 human bones, known as the Tokyo Human Bones, were found at the previous site of the Army Medical School in Tokyo, Japan, on July 22, 1989. They were located on the northern side of the previous location of the epidemic prevention research unit of the Army Medical School, with the discovery drawing a great deal of international attention. It was suggested that these bones might be from the victims of human experiments during World War II. It was found, in 1991, by Professor Sakura Shuo in Sapporo University, that the time and location of the burial of these bones was consistent with the existence of the Army Military Medical School. Most of these bones were Chinese, Korean and Mongolian races, and they were indeed closely related to the war. At the time they had not been found to be directly related to the human experiments of the Army Medical School, but the evidence left behind on the bones did not indicate gunshot or other war wounds, but evidence of medical experiments. This incident was known as the "Tokyo Bone Incident". Based on the research data on the Tokyo Human Bones internationally in the past 30 years, in particular, the testimony from the staff of the previous Army Medical School in Tokyo and members of the previous Army Medical School in Harbin (Unit 731), it can be concluded that some relationship exists between the Tokyo Human Bones and human experiments. This suggested that the nature of research related to these human bones conducted by the Army Medical School in Tokyo was consistent with those conducted at the Army Medical School in Harbin (Unit 731).

Abstract
Objective:To improve the diagnosis of the nose rhabdomyosarcoma.Method:Twenty-four patients with nose rhabdomyosarcoma were studied retrospectively.Result:Among 24 patients with nose rhabdomyosarcoma, three patients were in stage Ⅰ, four patients were in stage Ⅱ, eleven patients were in stage Ⅲ, and six patients were in stage Ⅳ. Embryonal rhabdomyosarcoma is the commonest in all the pathological types. Most patients need comprehensive therapy, including surgery operation, radiotherapy, and multicycle chemotherapy. Prognosis was poor in most of the cases. The survival rate of one year was 70.8% (17/24), and survival rate of three years was 30.3% (8/24).Conclusion:Different surgical protocols should be adopted for different patients, and postoperative chemoradiotherapy should be adopted for advanced treatment. By means of multidisciplinary collaboration, the patient's survival time would be prolonged.

Abstract
Tongkat Ali (Eurycoma longifolia Jack, family, Simaroubaceae) is traditionally used in Malaysia as health supplement for hypertension, diarrhea, aches, persistent fever, malaria, sexual insufficiency, dysentery, and glandular swelling. In this study, hydroalcoholic extract of Eurycoma longifolia Jack was studied for its antioxidant and in-vitro anti-inflammatory properties. The antioxidant activity (free radical scavenging) was evaluated to determine the total antioxidant capacity of extract Eurycoma longifolia Jack. The DPPH assay showed significant antioxidant activity in all concentrations (10, 25, 50,100 and 250 µg/ml). The antioxidant property of the extract was compared with the values of ascorbic acid, a standard antioxidant. Human RBC (HRBC) stbilization method was utilized to evaluate the in-vitro anti-inflammatory activity of the extract. The extract showed a significant anti-inflammtory activity in all the concentrations tested (25, 50,100, 250, 500 and 1000 µg/ml) and the activity was increased in a concentration dependent manner.

Abstract
With the cloning of cDNAs coding for the different phosphodiesterase 4 (PDE4) isoenzymes present in mammals, homogeneous preparations of these forms have become readily available. This strategy has greatly facilitated the understanding of the properties of the myriad of isoforms derived from the four PDE4 genes found in mammals, and has opened a new avenue to develop inhibitors with a different degree of selectivity for each isoform. Here we describe the strategies and methods used to express PDE4 in bacterial, yeast, insect, and mammalian cell heterologous systems, and review the advantages and disadvantages of each of these expression strategies. In addition, procedures to purify the recombinant proteins are described. The recently developed purification of a PDE4 by immunoaffinity chromatography provides a rapid and efficient method to prepare large quantities of PDE4. This method should be very useful for structural and kinetic studies on the PDE4D isoforms.

Abstract
A study was conducted to assess the measurement accuracy of a laser three-dimensional measurement system for measuring facial profile and to investigate the changes in lower facial morphology caused by experimental protrusion of the upper incisors, and also to examine the relationship between the changes in lip form and lip thickness. The study subjects were 24 Japanese male dental students attending Nihon University School of Dentistry at Matsudo, who had normal overbite, overjet, and normal occlusion, and a good facial profile. The mean age was 23.2 years with a range of 21.5 to 25.8 years. Three-dimensional measurements obtained by a computerized 3D laser scanning system were used to evaluate facial morphology. The measurement error of this system was less than 0.5 mm in any three-dimensional linear measurements. The stability and reproducibility of the recording procedure were evaluated. The changes in facial morphology caused by orthodontic treatment and orthognathic surgery were visualized in any direction by this three-dimensional graphic system. Lip thickness was not associated with changes in lip form. However, a relationship between the right and left corners of lip and lip thickness was noted. With regard to the ratio of changes in hard tissue and lips, the value of the original position for a 4 mm protrusion was not the same as that for a 4-8 mm protrusion. Also, the correlation of the changes in both groups was very low. The changes in lip thickness were associated with changes in stomion position, which in turn were related to the vertical change in the upper lip.

Abstract
Interleukin-12 (IL-12) is a heterodimeric cytokine that plays an important role in the regulation of the immune response. For biological activity the expression of both subunits of IL-12, p35 and p40, is required. Moreover, in the mouse the p40 chain of IL-12 specifically inhibits the effects of the IL-12 heterodimer. In the present study we have analyzed by in situ hybridization the expression of the p35 and p40 mRNA in the spleens of BALB/c and mutant (SCID, nude, beige) mice, unstimulated and after in vivo stimulation with lipopolysaccharide (LPS) and with staphylococcal enterotoxin B (SEB). In unstimulated spleens of BALB/c mice p35 and p40 mRNA were only detectable in a few strongly stained single cells, p35 mRNA was expressed in addition weakly in the B cell areas. After injection of LPS or SEB, p40 mRNA was strongly induced in the T cell areas all over the spleen, whereas expression of p35 mRNA and its distribution pattern did not change. Surprisingly, most of the mRNA for p35 and p40 was localized in different areas of the spleen and was apparently produced by different cells. In macrophage-depleted spleens the increased expression of p40 mRNA in response to LPS was reduced but still detectable, demonstrating that other cells besides macrophages can up-regulate IL-12 p40 mRNA. Nude mice showed a stronger expression of p35 mRNA, SCID mice lacked the weak p35 staining of the B cell areas but showed a strong basal expression of both p35 and p40 mRNA and a focal response to LPS. The pattern of IL-12 mRNA expression in beige mice was the same as in normal mice. These data demonstrate a spatial dissociation of expression of the two chains of IL-12 and are compatible with a regulatory role of the isolated IL-12 p40 chain in vivo. In addition, they indicate that the demonstration of mRNA for both chains of IL-12 in whole tissues or cell mixtures is not necessarily indicative of functional IL-12.

Abstract
At least two subsets of CD4+ T helper cell lymphocytes termed Th1 and Th2 exist in the mouse and probably in humans. They are characterized by the secretion of different lymphokines and by their functional behavior. Dysregulated expansion of one or the other subset may be one reason for the development of certain diseases. Thus, it is of importance to define the signals involved in the differentiation and activation of the two Th cell subsets. It is known and has been confirmed in this report that the cytokine interleukin (IL)-1 acts on Th2 cells but not on Th1 cells. We now report that a previously identified cytokine which was provisionally termed T cell stimulating factor is identical with IL-12 and exhibits a reciprocal behaviour to IL-1. IL-12 has several effects on Th1 cells. It can induce the proliferation of certain Th1 cells in combination with IL-2. Synthesis of interferon (IFN)-gamma by Th1 cells can be triggered by IL-2 plus IL-12. In contrast to the IFN-gamma production observed after T cell receptor (TcR) CD3 stimulation of Th1 cells with lectin Concanavalin A the IFN-gamma production induced by IL-12 + IL-2 is insensitive to the immunosuppressive drug cyclosporin A. Furthermore, IL-12 enhances the TcR/CD3-induced synthesis of IFN-gamma of several Th1 clones. Finally, IL-12 (+IL-2) induces homotypic cell aggregation of Th1 clones. This type of cell aggregation depends on the participation of LFA-1 and ICAM-1 molecules. In all activation systems with Th1 cells no effect of IL-1 was demonstrable. In contrast, only IL-1 but not IL-12 served as a co-stimulatory signal for several Th2 cell lines activated via the TcR/CD3 complex.

Abstract
The general way to induce the synthesis of lymphokines by T cells is the stimulation through the T cell receptor (TcR) complex which results in an increase of intracellular [Ca2+] and in the activation of a tyrosine kinase as well as of protein kinase C. Lymphokine production induced via the TcR is inhibited by the immunosuppressive drug cyclosporin A (CsA). However, an alternative pathway of lymphokine production exists. Several T lymphocyte clones can synthesize interferon-gamma (IFN-gamma), granulocyte-monocyte colony-stimulating factor, and small amounts of interleukin (IL3) when stimulated with syngeneic or allogeneic accessory cells (AC) plus IL2. In contrast to the TcR pathway the alternative pathway does not require a rise of intracellular [Ca2+] and is insensitive to the effects of CsA. In this report we provide evidence for the involvement of T cell-stimulating factor (TSF)--a probably novel murine cytokine--in the alternative pathway of lymphokine production. It is shown that fixation of the AC with carbodiimide or treatment of the AC with UV light greatly reduces their capacity to induce (in combination with IL2) the synthesis of IFN-gamma by T cells. This function is restored by addition of TSF. Moreover, TSF alone (without IL2) in combination with fixed AC can induce the synthesis of substantial amounts of IFN-gamma. Furthermore, TSF in combination with IL2 can stimulate freshly isolated spleen cells to produce IFN-gamma. The target cell resides probably in the non-B cell, non-T cell population.
