Abstract
Therapeutic effects of 9 antitumor drugs were studied on nude mice inoculated with transplanted human stomach tumor (MKN-28). When cisplatin, cyclophosphamide, chlormethine, 5-fluorouracil or mitomycin C was given ip to nude mice bearing MKN-28 at respective dose of 3, 100, 40, 80 and 2 mg/kg once weekly for 3 wk, the tumor inhibition rates of the former 3 drugs were over 80%, while the later 2 were 70-77%. Cytarabine 200 mg/kg twice or thrice weekly for 3 wk gave an inhibition rate of 68-72%. Hydroxycamptothecin 20 mg/kg twice weekly for 3 wk showed a better therapeutic effect than that given at 40 mg/kg once weekly for 3 wk, the tumor inhibition rates were 65 and 32% respectively. No apparent effect of vincristine and methotrexate on MKN-28 was seen. Histopathological observation indicated that in cisplatin group, numerous necrotic areas of tumor cells as well as sparse infiltration of inflammatory cells were found.

Abstract
Neutrophils have been implicated in the genesis of myocardial ischemia-reperfusion injury, and their mechanism of action has been linked to the production of reactive oxygen species, fatty acid-derived prostanoids, and leukotrienes. In this study, we examined the potential relation between production of reactive oxygen species and cyclooxygenase-derived autacoids by studying the effects of superoxide dismutase (SOD) and catalase (CAT) on the rise in thromboxane formation observed with myocardial ischemia and reperfusion. Immunoreactive thromboxane B2 was measured in cardiac lymph from conscious dogs during reperfusion after a 60-minute occlusion in the presence of infusions of SOD alone, CAT alone, and a combination of SOD and CAT. Reperfusion after 60 minutes of ischemia causes an immediate elevation in thromboxane B2. SOD and CAT infusion prevented this rise in thromboxane B2 as did infusion of SOD alone. The ability of SOD-CAT to suppress thromboxane B2 production dissipated within 3 hours after the cessation of infusion, at which time thromboxane B2 excretion increased. The modulation of fatty acid oxygenases by reactive oxygen species may be a very important pathogenic factor in considering the origin of the protective effect of antioxidants in the setting of myocardial ischemia-reperfusion injury.

Abstract
We have compared the acute toxicity, sub-acute toxicity and in vitro and in vivo anti-tumor action of the rude drug, stir-fried with rice, and alkali-processed drugs of Mylabris phalerata before and after removing the head, feet and wings. The results indicate that the toxicity of the processed drugs is lower than that of the rude ones; the toxicity becomes higher without head, feet, and wings; and the alkali-processing method is better than stir-frying with rice recorded in the pharmacopeia.

Abstract
Herbalogical study shows that Seman Cuscutae originated from Cuscuta chinensis is one of the most commonly used drugs in ancient times. Survey of botanical origins indicates that there are 9 species in Genus Cuscutae and 4 of them are commodities. The Cuscuta chinensis specified in current Chinese Pharmacopoeia (1985) is not the principal one.

Abstract
A radial immunodiffusion assay (RID) for human serum apolipoprotein A II (apo A II) was developed. Antisera to human apoA II were raised in goats with purified apoA II. The antibody-gel plate was prepared with 1% agarose. 5 microliters of each sample was added in a well. Diffusion was performed at 25 degrees C for 48 h. The minimum measurable concentration of apoA II was 58ng. The standard curve with a working range of 17.3-69 mg/dl was plotted. The coefficients of variation of within and between plates were 1.5-4.6% and 5.6% respectively. The recovery of the assay was 90.3-102.0%. The concentrations of apoA II for healthy men and women in Chengdu area were 26.7 +/- 4.4 mg/dl (n = 45) and 26.6 +/- 4.6 mg/dl (n = 31) respectively.

Abstract
This paper has shown that the pathologic damages done to rat's viscera due to hypoxic environment of altitude can be reduced significantly by oral administrations of Shengmaiyin, Danshen-Chuanxiong mixture and Rhodiola kirilowii. Shengmaiyin that maintains interior substances in the plate layer bodies proves more effective than Danshen-Chuanxiong mixture, while the latter excels in preventing capillary contraction, thus improving blood circulation. Rhodiola kirilowii has the effects of both Shengmaiyin and Danshen-Chuanxiong mixtures.

Abstract
Flux density distributions were measured in large tissue sections illuminated with 633- and 1064-nm laser radiation delivered by an optical fiber. The results were modeled by solving the 2-D diffusion approximation for an incident Gaussian beam and fitting the data with nonlinear regression. It is shown that the radial average flux density is exponentially attenuated for an arbitrary incident irradiance profile.

Abstract
An improved rate law for the CeIV-induced decomposition of HOOSO3- in aqueous H2SO4 has been established by study of the rate as a function of acidity. In aqueous HClO4 the rate is much faster but a rate law could not be obtained. Peroxydisulfate, by a variant of the AsIII and FeII analysis of the redox system, has been shown to be formed in the amount of half of the CeIV lost. A free-radical chain mechanism is postulated.

Abstract
The armamentarium of the pancreatic surgeon must include multiple operative techniques, to be adapted to the clinical and anatomical findings in the patient with chronic pancreatitis. Pancreaticoduodenectomy is an essential component of this armamentarium. Its indications and limitations require continued refinement. Pancreaticoduodenectomy (Whipple operation) provides excellent results in the relief of the pain of chronic pancreatitis. The incidence of reoperation for control of pain after this procedure is less than after drainage procedures. The postoperative mortality rate in recent report is less than 2%. Whereas resection of pancreatic tissue diminishes pancreatic function, the metabolic deficits are partially compensated by the better nutritional status resulting from pain relief and discontinuation of narcotics. In experienced hands, pancreaticoduodenectomy would appear to be the procedure of choice in patients with small pancreatic ducts. In selected patients, it appears to be a good procedure and, possibly, the operation of choice when the disease is predominantly present in the head of the pancreas and/or the uncinate process, especially when strictures involve the common bile duct and duodenum. The authors prefer the procedure when a hard, chronically-inflamed mass is present in the head of the pancreas. In our experience, if the suspicion of malignancy of the head of the pancreas persists at operation, pancreaticoduodenectomy is the procedure of choice. Before undertaking resection, the individual surgeon must assess his/her own experience; a low risk is essential. The continuing alcoholic is not a candidate for pancreaticoduodenectomy. Those who will not stop drinking should seldom be accepted for resection. The same limitation exists for the narcotic addict, but few such patients are encountered today. In the authors' experience, the operation is excellent for the relief of pain. It is the lifestyle of the continuing alcoholic that poses the more significant problem.

Abstract
An electrical impedance tomography (EIT) system has been constructed, operating at two frequencies, 40.96 and 81.92 kHz, for investigating the practicability of the dual-frequency imaging method discussed theoretically in a previous paper. For testing the system, a phantom with a frequency-dependent electrical conductivity was designed. The properties of the phantom can be adjusted to match the frequency dependence observed in a given type of tissue. Dual-frequency images were obtained from a phantom simulating liver and also from 200 g of porcine liver in a saline tank. Prior to image reconstruction, it was necessary to apply a correction to the data to cancel the effects of stray capacitance within the electronics.

Abstract
A number of p-aminohippuric acid analogues were synthesized in order to develop clinically useful 99mTc-labeled radiopharmaceuticals for evaluation of renal function measurements. Stable 99mTc-labeled complexes were formed at pH 5.7 using a Sn(II) reduction method with all derivatives. The newly synthesized complexes were screened utilizing biodistribution studies in small animals. All complexes were excreted via the GU tract within 60 min post iv administration, with no significant activity in GI tract and liver. The [99mTc]methyl-PAHIDA complex showed optimal biodistribution among these analogues. Further investigation is needed to determine if these derivatives may be used to replace [131I]o-iodohippuric acid for the evaluation of renal function.

Abstract
We studied the role of luteinising hormone (LH) and human chorionic gonadotropin (hCG) in regulation of rat granulosa cell inhibin production. Whereas pregnant mare serum gonadotropin (PMSG) or purified rat follicle-stimulating hormone (FSH) stimulated inhibin accumulation in culture media up to 6-fold in a dose-dependent manner, hCG or LH alone were without significant effect. Concomitant addition of hCG or LH to cultures containing half maximal or maximal stimulating concentrations of PMSG did, however, result in a dose-dependent inhibition of PMSG/FSH-induced inhibin production. However, in the 2-step culture system a biphasic effect of hCG treatment on FSH-primed granulosa cell inhibin and progesterone production was evident. hCG was only inhibitory when the cells in the 2-step system were primed with PMSG. These data indicate that granulosa cell inhibin production is under direct control of both FSH and LH, and provide a possible explanation for alterations in inhibin activity around the time of ovulation in vivo.

Abstract
When Actin Binding Protein (ABP) isolated from human blood platelets is phosphorylated in vitro with a cyclic AMP dependent kinase it becomes resistant to proteolysis by the Calcium Dependent Sulfhydryl Protease (CDSP). This protection against proteolytic cleavage is specific for CDSP since phosphorylation of ABP does not protect against proteolysis by trypsin, papain and thermolysin. Thus, there appears to be a distinct phosphorylation site on the ABP molecule which is essential for regulating the initial proteolytic degradation of ABP by CDSP.

Abstract
The antigenic structures capable of binding immunoregulatory T cells have been investigated. The functional properties (suppression or help) of BSA-specific T cells from primed or orally tolerized mice with capacity to adhere to bovine serum albumin or its peptic fragments were examined in reconstitution experiments in which splenic T-cell populations together with naive B cells were transferred into irradiated syngeneic recipients. Antigen-specific T suppressor cells isolated from mice tolerized to BSA adhered to peptic fragments of BSA as well as to the intact antigen. BSA-specific T helper cells adhered only to the intact antigen. Our data suggest that the preferential activation of T suppressor cells following administration of peptic fragments may be due to their ability to adhere to such fragments. These findings offer a novel approach of separation and identification of T suppressor cells and may be useful in further studies of immunosuppression.

Abstract
Radioiodinated recombinant human beta-interferon (rHuIFN beta Ser), with almost full (greater than 90%) biological activity, was used to study the binding of human beta-interferon to Daudi cells. Specific binding was not observed with less biologically active (less than or equal to 10%) radioiodinated interferon. The bound radioiodinated interferon was shown to compete with human beta-interferon (HuIFN beta), rHuIFN beta Ser, human alpha-interferon (HuIFN alpha) and with human gamma-interferon (HuIFN gamma). Scatchard plot analyses suggest the presence of about 10,000 binding sites for HuIFN beta/Daudi cell. About 6,600 of these sites can be blocked by HuIFN alpha and 3,700 sites can be blocked by HuIFN gamma. The apparent Kd for HuIFN beta is 2.7 nM. The apparent Kd values for HuIFN alpha and HuIFN gamma are 3.7 and 1.1 nM, respectively. It was possible to demonstrate the cross-linking of HuIFN beta to two macromolecular components of Mr = 128,000 and 103,000. We propose the existence of at least two binding sites for HuIFN beta in Daudi cells, one site recognizing both HuIFN beta and HuIFN gamma, the other site recognizing both HuIFN beta and HuIFN alpha. Each site is capable of recognizing only HuIFN gamma or HuIFN alpha.

Abstract
The amino acid sequence of the ubiquinone binding protein (QP-C) in the cytochrome bc1 region of the mitochondrial electron transfer chain was determined by analysis of peptides obtained by cyanogen bromide cleavage and staphylococcal protease digestion of succinylated derivatives. It was found to consist of 110 amino acid residues and its amino terminus to be blocked by an acetyl group, as determined by mass spectrometry of the amino-terminal peptide and a comparison with peptides chemically synthesized on high-performance liquid chromatography. The molecular weight of this ubiquinone binding protein including the acetyl group was calculated to be 13,389. The predicted secondary structure of QP-C has alpha-helical content of about 50% and QP-C was classified as an "all-alpha" or "alpha + beta" protein. This is the first report describing the amino acid sequence of the ubiquinone binding protein. A comparison of this sequence with that of the 14-kDa subunit of the yeast ubiquinol-cytochrome c reductase complex from the nucleotide sequence showed these two sequences to be quite similar.
