Abstract
OBJECTIVE Self-harm and attempted suicide are risk factors for suicide in psychiatric hospital in-patients. This study aimed to analyse the circumstances of self-harm and suicide attempts in a Japanese psychiatric hospital so as to improve management and care. METHODS Incident reports of self-harm and suicide attempts during a 12.4-year period from November 2000 to March 2013 were reviewed. A descriptive analysis was conducted in terms of age, sex, and diagnosis of patients, as well as level, ward, situations, and causes of incidents. RESULTS During the study period, 90 cases of self-harm and attempted suicide involving 58 patients were reported. The rate of self-harm and suicide attempts was 0.05 per 1000 patient-days. The types of selfharm and suicide attempts included hanging (n = 25), wrist cutting (n = 19), ingestion of foreign objects (n = 17), and others (n = 29). The single case of completed suicide involved hanging, in a patient with schizophrenia. Among 55 patients with relevant data, the most common clinical diagnosis was mood disorder (41.8%), followed by schizophrenia (36.4%). Mood disorder was 3.5 times as prevalent in females as in males (14 vs. 4). Fourteen patients with mood disorder (n = 8) or schizophrenia (n = 6) were repeatedly involved in 46 of 89 cases of self-harm or attempted suicide; 11 were female. One woman with mood disorder attempted suicide 9 times within the same year. The top 3 management and care factors related to self-harm and suicide attempts were failure to adhere to preventive procedures (28%), insufficient therapeutic communication (28%), and difficulty in predicting suicide (20%). CONCLUSION Self-harm and suicide attempts at this psychiatric hospital occurred at a rate of 0.05 per 1000 patient-days between late 2000 and early 2013. Efforts are needed to increase compliance with suicide prevention procedures and therapeutic communication, so as to improve management and care of psychiatric in-patients and prevent them from committing suicide.

Abstract
BACKGROUND The laparoscopic procedure involving total resection of abdominal neuroblastoma combined with lymphadenectomy has not been reviewed in English literature. The aim of this study was to evaluate the significance and accuracy of laparoscopic resection of abdominal neuroblastoma. METHODS Since July 1997, five patients with abdominal neuroblastoma underwent laparoscopic resection combined with lymphadenectomy or sampling of the lymph nodes. The length of operation, intraoperative blood loss, resectability, and complications were retrospectively reviewed and evaluated. RESULTS Four cases were managed laparoscopically, but one case was converted to open procedure because of poor visualization around large vessels. The mean operation time was 135 min and the intraoperative blood loss 52 ml. CONCLUSIONS Good visualization of the primary tumor and large vessels is, arguably, the most important factor for successful completion of this procedure laparoscopically. Precise indicators for laparoscopic resection of abdominal neuroblastoma provide a better prognosis and a good quality of life for children with neuroblastoma.

Abstract
AIM The serum undercarboxylated osteocalcin (ucOC) level, a biochemical bone marker of vitamin K insufficiency, is often affected by anti-osteoporosis drugs. There have been no reports regarding the relationship between ucOC and teriparatide. SUBJECTS AND METHODS We conducted a prospective observational study of 26 female rheumatoid arthritis (RA) patients. The patients were divided into 3 groups: those who underwent a direct switch from anti-resorptive drugs to teriparatide (12 cases), those who started teriparatide without pre-treatment (5 cases), and the control patients (9 cases). The median age (interquartile range) of the patients in each group was 75 (67-77), 82 (78-84), and 69 (62-80) yr, respectively. All patients, except controls, received 48-week treatments of teriparatide. We analyzed the median 48-week changes from baseline of the serum ucOC levels with the Steel-Dwass method. RESULTS The median change from baseline in the direct switch group was higher than that in other groups (p<0.05). CONCLUSIONS The serum ucOC levels increased with treatment of teriparatide in elderly RA patients, especially when the patients received pre-treatment.

Abstract
BACKGROUND Serum undercarboxylated osteocalcin (ucOC) is a biochemical bone marker of vitamin K insufficiency. It had been reported that bone resorption inhibitors tend to decrease the serum ucOC level in patients with primary osteoporosis. In rheumatoid arthritis (RA) patients, these results have never been reported. AIM We investigated risk factors which could change serum ucOC level in post-menopausal women with RA (no.=100). SUBJECTS AND METHODS Twenty patients received no bone resorption inhibitor (control), 30 received raloxifene (RLX), while 50 received alendronate (ALN). This cross-sectional study was limited to patients with low RA disease activity (Disease Activity Score-28 ≤3.2). We measured serum ucOC, and the data were analyzed by multivariable analysis, including ucOC and the other variables. RESULTS Scheffe's F test demonstrated a significant difference in serum ucOC levels between controls and the RLX group (p<0.01), and between controls and the ALN group (p<0.01). Serum ucOC levels were low in both treated groups. An adjusted multivariate analysis was performed for the variables: bone resorption inhibitor use, serum alkaline phosphatase, glucocorticoid dose, age, estimated glomerular filtration rate and matrix metalloproteinase 3. As a result, serum ucOC inversely correlated with bone resorption inhibitor use (p<0.01) and oral glucocorticoid dose (p<0.01), which were independent risk factors of lowering ucOC. CONCLUSIONS Bone resorption inhibitors and glucocorticoids were independent risk factors for lowering serum ucOC levels in post-menopausal RA patients.

Abstract
OBJECTIVE: Glycaemic control is critical to prevent diabetic complications and mortality. This 6-month, open-label, observational study assessed the efficacy and safety of switching Japanese patients with type 2 diabetes from neutral protamine Hagedorn (NPH) insulin to insulin detemir. METHODS: Patients with type 2 diabetes ( n = 126) receiving basal—bolus insulin therapy with NPH insulin plus rapid-acting insulin analogues were recruited. NPH insulin was replaced with insulin detemir for 6 months. Glycosylated haemoglobin (HbA1c), fasting plasma glucose (FPG), daily glucose levels and hypoglycaemia were monitored. Nocturnal quality of life was assessed by insulin therapy related quality of life at night questionnaire. RESULTS: HbA1c, FPG and body weight were all significantly reduced after treatment with insulin detemir for 6 months, without increasing severe hypoglycaemia. Insulin dose increased significantly over the same time. There were significant improvements in overall nocturnal quality of life, as well as well-being. CONCLUSIONS: Treatment with insulin detemir for 6 months resulted in substantial benefits, including reduced HbA1c, FPG and body weight, and improvements in nocturnal quality of life, without increasing hypoglycaemia.

Abstract
It is sometimes difficult to confirm the location of a microadenoma in Cushing disease.
Recently, we experienced an 11-yr-old female case of Cushing disease with
hyperprolactinemia. She was referred to our hospital because of decrease of height
velocity with body weight gain. On admission, she had typical symptoms of Cushing
syndrome. Although no pituitary microadenomas were detected on 1.5 Tesla MRI of the brain,
endocrinological examinations including IPS and CS sampling were consistent with Cushing
disease with hyperprolactinemia. Oral administration of methyrapone instead of
neurosurgery was started after discharge, but subsequent 3 Tesla MRI of the brain clearly
demonstrated a 3-mm less-enhanced lesion in the left side of the pituitary gland. Finally,
transsphenoidal surgery was performed, and a 3.5-mm left-sided microadenoma was resected.
Compared with 1.5 Tesla MRI, 3 Tesla MRI offers the advantage of a higher signal to noise
ratio (SNR), which provides higher resolution and proper image quality. Therefore, 3 Tesla
MRI is a very useful tool to localize microadenomas in Cushing disease in children as well
as in adults. It will be the first choice of radiological examinations in suspected cases
of Cushing disease.

Abstract
The pathogenesis of gastroschisis (GS) is controversial. We present a case of GS complicated by colonic atresia and arthrogryposis multiplex congenita. This association is attributed to intrauterine vascular compromise. Furthermore, a probable omphalomesenteric artery (OMA) remnant was found on the right side of the defect opposite the umbilicus and extended with bifurcation to the mesenteries of the colon and ileum, between which colonic atresia occurred. This provided further evidence in support of the hypothesis that GS is caused by an intrauterine interruption of OMA.

Abstract
OBJECTIVE Growth hormone (GH) has been reported to have a potent effect on the immune system. However, the detailed mechanism of the effect of GH on the immune system has not yet been clarified. This study was designed to investigate the nature of this mechanism. METHODS In the present study, we investigated the effects of GH on the susceptibility of both human CEM/C7 lymphocytes and human IM-9 lymphocytes to Fas-induced apoptosis. RESULTS Both cell lines expressed GH receptor mRNA. GH rescued Fas-induced suppression of [(3)H]-thymidine incorporation into each cell line. GH prevented Fas-induced apoptosis in each cell line without changing Fas antigen expression. We next investigated the mechanisms of the prevention of Fas-induced apoptosis, by focusing on intracellular molecules related to the apoptotic signal. Bcl-2 expression was increased by GH treatment in both CEM/C7 and IM-9 lymphocytes. GH also downregulated caspase-3 expression and inhibited activation of caspase-3 in both cell lines. CONCLUSION These findings suggest that GH regulates the human immune system through inhibition of Fas-induced apoptosis in activated T and B lymphocytes.

Abstract
Oocytes of the starfish, Asterina pectinifera, are arrested at the G2 phase of meiosis I and possess a prominent germinal vesicle in which maternal stores of nuclear proteins which are destined for use primarily by the early embryo are stored. Germinal vesicle breakdown and subsequent oocyte maturation is triggered by activation of the p34(cdc2)/cyclin B complex, which is present as the preform in the cytoplasm. The aim of the present study was to identify and biochemically characterize in vivo substrates of the kinase. Two nucleic acid binding nuclear proteins designated NAAP1 and NAAP2 were found, both of which contain 345 amino acid residues with pI 3. 6 and which serve as substrates. The only difference between the two proteins was in the primary amino acid sequence at position 51, which is Asn in NAAP1 but Thr in NAAP2. NAAPs are phosphorylated in vivo during oocyte maturation but not at the meiotic G(2) stage. NAAPs are phosphorylated in vitro by the cdc2 kinase on the same site as in vivo. Although there are other evolutionarily conserved consensus sequences for phosphorylation by mitotically active cdc2 kinase in NAAPs and NAAP-derived fragments containing the sequences were efficiently phosphorylated in vitro, these sites in the intact NAAPs were not phosphorylated either in vivo or in vitro. These results suggest that the tertiary structure of NAAPs affects the target specificity of the cdc2 kinase.

Abstract
In response to 1-methyladenine, a maturation-inducing substance, starfish oocytes undergo reinitiation of meiosis with germinal vesicle breakdown through activation of p34cdc2-cyclin B, which results in the dispersal of the nucleolus. Little information has been elucidated thus far on nucleolar proteins that are phosphorylated by p34cdc2-cyclin B during meiotic maturation. Here, we describe a novel nucleolar protein of the starfish Asterina pectinifera oocyte, which is designated ANO39 and which is phosphorylated during meiotic maturation. A full-length ANO39 cDNA of 2106 base pairs encodes a polypeptide of 346 amino acids having a calculated Mr of 39 005. The amount of ANO39 is kept nearly constant during oocyte maturation and embryogenesis up to the midgastrula stage. The transcript encoding ANO39 was present in growing oocytes but not in full-grown ones, as evidenced by Northern blot hybridization. Ser145 is specifically phosphorylated when ANO39 is incubated in vitro with purified starfish p34cdc2-cyclin B. This phosphorylation site corresponds to that is phosphorylated during meiotic maturation in vivo. Immunoblot analysis using phosphoserine145-specific antibody as a probe revealed that some populations of ANO39 of the immature oocytes at the G2 stage have been already phosphorylated on Ser145 and Ser145 is maximally phosphorylated during meiotic maturation.

Abstract
OBJECTIVE To evaluate efficacy of low dose prednisolone maintenance in patients with primary Sjögren's syndrome. METHODS An open, prospective pilot study of prednisolone for the treatment of 20 patients with primary Sjögren's syndrome was performed. Evaluations included the amount of whole saliva measured by the Saxon test, serological abnormalities and oral symptoms. RESULTS Initial dosage of prednisolone was 15.0+/-1.5 (mean+/-SEM) mg/day. Maintenance dosage was 7.5-5.0 mg/day. Follow-up period was 26.3+/-3.8 months (range 3-48). The amount of whole saliva significantly increased after 1 month of prednisolone therapy and the increase continued up to 48 months by maintaining low-dose prednisolone. A mean percent increase of whole saliva from baseline ranged from +105.2+/-36.2% to +245.7+/-82.1%. Serum IgG, anti-SS-A/Ro, anti-SS-B/La antibodies and IgM rheumatoid factor levels significantly decreased throughout the study with partial decreases of IgA and IgM levels. The improvement of subjective oral symptoms was also confirmed. CONCLUSION Low-dose prednisolone maintenance may have a worthwhile clinical benefit in patients with primary Sjögren's syndrome that deserves further evaluation in a controlled trial.

Abstract
BACKGROUND Oxidized LDL increases the production of both prostaglandin E2 (PGE2) and thromboxane B2 (TXB2) in rat mesangial cells. These increases were suppressed by antioxidants such as alpha-tocopherol (alpha-Toc) or probucol. METHODS We investigated the mechanism by which oxidized LDL leads to an increase in PGE2 production using rat mesangial cells in culture. We also examined how alpha-Toc supresses this augmentation, by measuring intracellular Ca2- and phospholipase A2 (PLA2) activity. RESULTS In rat mesangial cells, oxidized LDL increased PLA2 activity by increasing the intracellular calcium ion content, which resulted in the induction of PGE2 production. On the other hand, pretreatment of cells with alpha-Toc, which resulted in a large uptake of alpha-Toc in cell membranes, markedly suppressed the augmentation of PGE2 production and PLA2 activity by oxidized LDL in a dose dependent manner. However, cytosolic PLA2 partially purified from mesangial cells was not inhibited by alpha-Toc despite an increase of alpha-Toc. CONCLUSION These results suggest that the augmentation of PLA2 activity in mesangial cells by oxidized LDL in a result of oxidative stresses, and that the antioxidant action of alpha-Toc is responsible for the suppression of augmentation of PLA2 activity observed in mesangial cells exposed to oxidized LDL.

Abstract
Mouse ileal sodium dependent bile acid transporter (ISBT) was characterized using isolated enterocytes. Only enterocytes from the most distal portion showed Na+-dependent [3H]taurocholate uptake. Northern blot analysis using a probe against mouse ISBT revealed the expression of mouse ISBT mRNA to be restricted to the distal ileum. The Km and Vmax for Na+-dependent [3H]taurocholate transport into isolated ileocytes were calculated as 27 microM and 360 pmol/mg protein/min, respectively. Uptake of [3H]taurocholate was inhibited by N-ethylmaleimide. We have cloned ISBT cDNA from mouse ileum. The cDNA included the entire open reading frame coding 348 amino acid protein with seven hydrophobic segments and two N-glycosylation sites. COS-7 cells transfected with the expression vector containing this cDNA expressed Na+-dependent [3H]taurocholate uptake activity with a Km of 34 microM.

Abstract
We reported a 68-old female who was diagnosed to have systemic lupus erythematosus 18 years ago. She had been well under 5 mg of prednisolone until 1995, when she felt severe shortness of breath. Laboratory examinations disclosed severe anemia accompanying mild thrombocytopenia. Bone marrow aspiration revealed a complete absence of erythroid progenitor cells. She was diagnosed to have pure red cell aplasia (PRCA) as well as antiphospholipid syndrome. A judicious use of methylprednisolone including pulse therapy resulted in a prompt resolution of anemia as well as thrombocytopenia and the dose of corticosteroid was tapered successfully thereafter. Persistent infection of HPV B 19 in the patient with inactive SLE was considered as a main cause of PRCA because not only IgG-HPV B 19 antibody but viral DNA was demonstrated in her serum at the time of admission. The relationship between PRCA and anti-phospholipid syndrome in this patient was also noted.

Abstract
Depending upon the type of cancer involved, the period of the end stage varies greatly, and with it decreases the quality of life (QOL). In gastric cancer, for example, the terminal stage is usually short and the QOL diminishes abruptly. Thus, it takes time keeping this decrease in QOL to minimum, despite the complications, so that the patient's last days will be even somewhat more acceptable. Improvement in QOL for the patient who cannot eat due to recurrent gastric cancer can be effectively achieved by alleviation through IVH. With this in mind, the conditions consonant with the application of home IVH are as follows: 1) The patient's pain can be kept under control at home. 2) The patient wishes to remain. 3)There is sufficient human support at home. The caretakers in the family, and especially the key person(s) must exert much effort and labor and they need rest as well. Home medical care in the terminal stage presupposes a social environment involving day care, short stay, and hospice nursing facilities of all kinds. At present, public services of this kind differ with the community, much remains uninformed to public, and clinic-hospital networking will be needed more than ever. In this difficult situation, the home-care medical services provided by the private sector are effective. These services are only for the short term, of course, and there will be a financial problem. Various measures (tax deduction, public assistance) must be considered to support the patients and caretakers.

Abstract
The three-dimensional ultrastructure of glomerular basement membrane (GBM) and mesangium in very early stage of streptozotocin-induced diabetic rat kidney was examined by the quick-freezing and deep-etching method. In control rats GBM was composed of three layers. Outer and inner layers consisted of files of fibrils that connected endothelial or epithelial cells perpendicularly with meshwork of a middle layer that also consisted of dense meshwork structure composed of fibrils. In diabetic rats, perpendicular fibrils of the inner layer were irregular and disrupted, and the layer was enlarged. The meshwork structure of the middle layer was irregularly enlarged, and matrix fibrils were disrupted. Early insulin treatment prevents these morphological changes. Furthermore, early administration of beraprost sodium, a PGI2 analogue, might have beneficial effects in preventing the progression of these changes.

Abstract
The effects of the new 5-HT2A receptor antagonist sarpogrelate on the cellular action of serotonin were examined in cultured rat mesangial cells by measuring cytosolic free calcium concentration ([Ca2+]i). Sarpogrelate inhibited serotonin-induced increases in [Ca2+]i in a concentration-dependent manner. M1, a major metabolite of sarpogrelate, also exhibited an inhibitory effect exceeding that of sarpogrelate. The inhibitory effects of sarpogrelate and M1 were abolished by washing out these compounds. In contrast, the increase in [Ca2+]i induced by angiotensin II or arginine vasopressin was not affected by pretreatment of the cells with sarpogrelate or M1. These results suggest that sarpogrelate and its major metabolite (M1) act as reversible and specific 5-HT2A receptor antagonists against the contractile action of platelet-derived serotonin in mesangial cells.

Abstract
We examined two groups of non-insulin-dependent diabetic men (group A, 13 patients without microalbuminuria; group B, 9 patients with intermittent microalbuminuria) to ascertain whether the anaerobic threshold (AT) can provoke microalbuminuria, comparing them with 12 healthy subjects matched for age and sex (group C). All subjects exercised on a bicycle ergometer until the AT was reached. In intermittent microalbuminuria, the albumin:creatinine ratio (ACR) was over 0.25 mg/mmol.Cr 1-3-fold in 5 measurements. The ACR after exercise was increased to over 0.25 mg/mmol.Cr in 4/9 cases in group B (P < 0.05), in 2/13 cases in group A, but not at all in group C. We also studied the mechanism of exercise-induced microalbuminuria. In group B, ACR before exercise correlated positively with the baseline plasma glucose. Furthermore, positive correlation was found between ACR after exercise and HbA1c in group B. The AT did not affect the urinary beta 2-microglobulin in any groups. The plasma atrial natriuretic factor (ANF) after exercise was elevated most prominently in group B (P < 0.05). Positive correlation was found between increments of ACR and increments of plasma ANF after exercise in group B. We conclude that the AT can provoke microalbuminuria in some non-insulin-dependent diabetics. The plasma ANF and metabolic control may play an important role in the pathophysiology of exercise-induced microalbuminuria.

Abstract
In an attempt to elucidate the relationship between the progress of glomerular injury and abnormalities of lipid metabolism, we investigated glomerular deposition of apolipoprotein B (apo B) in renal biopsy specimens from 60 patients with glomerular diseases by indirect immunofluorescence using antihuman apo B-100 monoclonal antibody in comparison with clinical and histopathological findings. The patients were divided into 2 groups according to the intensity in staining of apo B in glomerulus (group A: negative or weakly positive; and group B: definitely positive). Staining of apo B in glomerulus was found in 37 patients (62%). The levels of serum total cholesterol, phospholipids, low density lipoprotein cholesterol and apo B in group B were significantly higher than in group A. The urinary protein excretion in group B was greater than that in group A. Group B was also shown to have a significantly decrease in renal function. Light microscopy revealed severe mesangial proliferation in patients with IgA nephropathy of group B. These findings suggested that glomerular apo B containing-lipoprotein deposition may play an important role in the progression of glomerular injury.

Abstract
We compared heart rates at the anaerobic threshold (AT) with age-adjusted heart rates in two groups of diabetics (DMY, mean age 31; and DMO, mean age 48) to ascertain whether the AT is useful for evaluating the intensity of exercise therapy for diabetics. In both the DMY and DMO groups the AT was reached at lower heart rates than in control groups of healthy subjects, indicating that the metabolism of diabetics may become anaerobic if their age-adjusted heart rate is higher than their heart rate at the AT. In this study, 86% of the DMY and 50% of the DMO group had age-adjusted heart rates, at 70% of maximum, that were higher than the heart rates at the AT. Thus, exercise intensity with an age-adjusted heart rate at 70% of maximum may induce anaerobic metabolism in some diabetics. We also studied the relationship between exercise intensity and the glycosylated hemoglobin (HbA1c) level at the AT in order to understand why the heart rate at the AT in diabetics was less than in healthy subjects. Exercise intensity at the AT in both diabetic groups was less than in healthy groups, and so did not increase the heart rates. Both exercise intensity and the heart rate at the AT were inversely related to the HbA1c level, suggesting that HbA1c may be important for keeping low the exercise intensity and the heart rate at the AT. As far as possible, we excluded cardiovascular autonomic neuropathy, so that it could not explain the mechanism.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
To investigate the role of extracellular Ca2+ (Ca2+) in suppression of glucagon release in diabetic animals, pancreata were isolated from streptozotocin-diabetic rats and perfused with a 15 mM glucose solution containing one of the following: (1) Ca2+ 2.1 mM and insulin 22 microU/ml, (2) Ca2+ 2.1 mM and insulin 110 microU/ml, (3) Ca2+ 2.1 mM and insulin (-) or (4) Ca2+ 0.2 mM and insulin 110 microU/ml. Although perfusion with 22 microU/ml of insulin did not alter glucagon release, perfusion with 110 microU/ml of insulin in the presence of Ca2+ and glucose significantly reduced the release of glucagon from 1.9 +/- 0.3 ng/min to 1.2 +/- 0.3 ng/min for the first 3 min. The absence of insulin enhanced glucagon release from the baseline level of 1.0 +/- 0.1 ng/min to 1.6 +/- 0.3 ng/min at 11 min and to 1.4 +/- 0.2 ng/min at 21 min. Deprivation of Ca2+ in the perfusate also enhanced glucagon release from the baseline level of 0.8 +/- 0.1 ng/min to 1.2 +/- 0.3 ng/min for the first 4 min. It is concluded that insulin suppresses glucagon release and Ca2+ is needed for the suppression of glucagon release in the presence of both insulin and glucose in streptozotocin-diabetic rat pancreata.

Abstract
The recent findings that alpha-glucosidase from human kidney was identical with one component (F1) of the alpha-glucosidases found in human urine suggested the idea that this enzyme might originate in the kidneys. The present study was performed to test this idea by immunological methods. Urine alpha-glucosidase F1 was isolated in the electrophoretically homogeneous state, and the antibody prepared in rabbits was purified by affinity chromatography after the antisera were fractionally precipitated with ammonium sulfate and chromatographed on diethylamino ethyl (DEAE)-cellulose. The staining of human kidney tissue sections was performed by the indirect method, using alpha-glucosidase F1 antibody and fluorescein-conjugated anti-rabbit immunoglobulin goat sera. The proximal convoluted portion (proximal tubules) with brush border and Henle's loops (late proximal) were stained clearly. Preincubation of intact antibody with purified antigen prevented specific staining of the proximal convoluted portion and Henle's loops. In contrast, all other tissues of kidney were stained less positively or negatively. These results indicate that alpha-glucosidase F1 originates in the kidney, and that glucosidase is specifically localized in the proximal convoluted portion and Henle's loops.

Abstract
alpha-Glucosidase was extracted from a homogenate of human kidney, initially with 0.02 M Tris-HCl buffer, pH 7.6, and subsequently with a mixture of 0.5% cholate and 0.5% Triton X-100 in the same buffer, pH 7.6. The enzyme in each of these two fractions was purified to the electrophoretically pure state by fractional precipitation with ammonium sulfate, column chromatographies on DEAE-cellulose, hydroxyapatite, Bio Gel A-1.5 m and affinity chromatography on heated glutinous rice. The two purified alpha-glucosidase preparations obtained were the same in enzymatic and proteochemical properties, and the molecular weight and isoelectric point estimated were 3 x 10(5) and 4.2, respectively. No evidence for subunit structure was obtained. The optimum pH for activity was 5.6 and the activity was drastically inhibited by Nojirimycin. The alpha-glucosidase readily hydrolyzed maltose, starch, and glycogen, producing only glucose. It hydrolyzed maltotriitol to split the non-reducing end glucose, but scarcely hydrolyzed maltitol or various other heteroglucosides examined. All these proteochemical and enzymatic properties of kidney alpha-glucosidase were the same as those of urine F-1 alpha-glucosidase. Also, kidney tissue alpha-glucosidase produced a clear precipitin line with antisera against urine F-1 alpha-glucosidase. These facts suggest that F-1 alpha-glucosidase in urine originates from kidney tissue.

Abstract
The effects of niceritrol, a nicotinic acid derivative, on the levels of HDL-cholesterol (HDL-Ch) and a mixture of VLDL- and LDL-Ch (VLDL- + LDL-Ch) were studied in hyperlipidemic patients. Serum total cholesterol (sTC) and serum triglyceride (sTG) were significantly reduced during niceritrol administration. Lipoprotein electrophoresis showed that niceritrol increased the alpha:beta ratio. HDL-Ch showed a significant increase of 12.5% by the 16th week of therapy. This increase was more marked in patients with lower pre-treatment HDL-Ch levels and significant in patients whose pre-treatment sTG levels were in excess of 200 mg/dl. Females displayed higher pre-treatment HDL-Ch levels (38.5 mg/dl) than males (30.6 mg/dl). However, niceritrol increased HDL-Ch significantly in both groups. At 16 weeks, the VLDL- + LDL-Ch level showed a significant decrease of 9.2%; the HDL-Ch:VLDL + LDL-Ch and HDL-CH:sTC ratios were significantly increased throughout niceritrol administration. Niceritrol is thought to be effective in preventing the development and progression of atherosclerosis because it raises the level of anti-atherogenic HDL-Ch and lowers the level of atherogenic VLDL- + LDL-Ch.
