Abstract
A number of RORγ inhibitors have been reported over the past decade. There were also several examples advancing to human clinical trials, however, none of them has reached the market yet, suggesting that there could be common obstacles for their future development. As was expected from the general homology of nuclear receptor ligands, insufficient selectivity as well as poor physicochemical properties were identified as potential risks for a RORγ program. Based on such considerations, we conducted a SAR investigation by prioritizing drug-like properties to mitigate such potential drawbacks. After an intensive SAR exploration with strong emphasis on "drug-likeness" indices, an orally available RORγ inhibitor, JTE-151, was finally generated and was advanced to a human clinical trial. The compound was confirmed to possess highly selective profiles along with good metabolic stability, and most beneficially, no serious adverse events (SAE) and good PK profiles were observed in the human clinical trial.

Abstract
Rheumatoid arthritis (RA) is an autoimmune disease characterized by inflammation and the destruction of bone and cartilage in affected joints. One of the unmet medical needs in the treatment of RA is to effectively prevent the structural destruction of joints, especially bone, which progresses because of resistance to conventional drugs that mainly have anti-inflammatory effects, and directly leads to a decline in the QOL of patients. We previously developed a novel and orally available type II kinase inhibitor of colony-stimulating factor-1 receptor (CSF1R), JTE-952. CSF1R is specifically expressed by monocytic-lineage cells, including bone-resorbing osteoclasts, and is important for promoting the differentiation and proliferation of osteoclasts. In the present study, we investigated the therapeutic effect of JTE-952 on methotrexate (MTX)-refractory joint destruction in a clinically established adjuvant-induced arthritis rat model. JTE-952 did not suppress paw swelling under inflammatory conditions, but it inhibited the destruction of joint structural components including bone and cartilage in the inflamed joints. In addition, decreased range of joint motion and mechanical hyperalgesia after disease onset were suppressed by JTE-952. These results suggest that JTE-952 is expected to prevent the progression of the structural destruction of joints and its associated effects on joint motion and pain by inhibiting CSF1/CSF1R signaling in RA pathology, which is resistant to conventional disease-modifying anti-rheumatic drugs such as MTX.

Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by synovial inflammation and structural destruction of the joints. Bone damage occurs in an early stage after onset and osteoclast activation plays a substantial role in its progression. Colony stimulating factor 1 receptor (CSF1R) is a receptor protein tyrosine kinase specifically expressed in monocytic-lineage cells such as macrophages and osteoclasts. Here, we investigated the effect of JTE-952, a novel CSF1R tyrosine kinase inhibitor, on osteoclast formation in vitro and on bone destruction in a mouse model of collagen-induced arthritis. JTE-952 completely inhibited osteoclast differentiation from human monocytes, with an IC50 of 2.8 nmol/L, and reduced osteoclast formation from the synovial cells of RA patients. Detectable levels of colony stimulating factor 1 (CSF1), a ligand of CSF1R, were observed in the synovial tissues of the arthritis model, similar to those observed in the pathology of human RA. JTE-952 significantly suppressed increases in the bone destruction score, the number of tartrate-resistant-acid-phosphatase-positive cells, and the severity of arthritis in the model mice. We also examined the efficacy of JTE-952 combined with methotrexate. This combination therapy more effectively reduced the severity of bone destruction and arthritis than monotherapy with either agent alone. In summary, JTE-952 potently inhibited human osteoclast formation in vitro and suppressed bone destruction in an experimental arthritis model, especially when combined with methotrexate. These results indicate that JTE-952 should strongly inhibit bone destruction and joint inflammation in RA patients and effectively prevent the progression of the structural destruction of joints.

Abstract
Here, we have constructed neural network-based models that predict atomic partial charges with high accuracy at low computational cost. The models were trained using high-quality data acquired from quantum mechanics calculations using the fragment molecular orbital method. We have succeeded in obtaining highly accurate atomic partial charges for three representative molecular systems of proteins, including one large biomolecule (approx. 2000 atoms). The novelty of our approach is the ability to take into account the electronic polarization in the system, which is a system-dependent phenomenon, being important in the field of drug design. Our high-precision models are useful for the prediction of atomic partial charges and expected to be widely applicable in structure-based drug designs such as structural optimization, high-speed and high-precision docking, and molecular dynamics calculations.

Abstract
Starting from a previously reported RORγ inhibitor (1), successive efforts to improve in vivo potency were continued. Introduction of metabolically beneficial motifs in conjunction with scaffold hopping was examined, resulting in discovery of the second generation RORγ inhibitor composed of a 4-(isoxazol-3-yl)butanoic acid scaffold (24). Compound 24 achieved a 10-fold improvement in in vivo potency in a mouse CD3 challenge model along with significant anti-inflammatory effects in a mouse dermatitis model.

Abstract
Optimization of novel azetidine compounds, which we had found as colony stimulating factor-1 receptor (CSF-1R) Type II inhibitors, provided JTE-952 as a clinical candidate with high cellular activity (IC50 = 20 nM) and good pharmacokinetics profile. JTE-952 was also effective against a mouse collagen-induced model of arthritis (mouse CIA-model). Additionally, the X-ray co-crystal structure of JTE-952 with CSF-1R protein was shown to be a Type II inhibitor, and the kinase panel assay indicated that JTE-952 had high kinase selectivity.

Abstract
The LDA (lithium diisopropylamide)-promoted regiocontrolled halogen dance of α-bromothiophenes and α-bromofurans is described. Bromothiophenes bearing a diethyl acetal moiety undergo selective deprotonation at the β-position adjacent to the bromo group. In contrast, oxazoline, ester, and amide groups act as directing groups in the initial lithiation step to generate a carbanion at the β-position neighboring the directing group to exclusively give the other regioisomer. These results can be applied to the regiocontrolled halogen dance of bromofuran derivatives.

Abstract
A novel series of RORγ inhibitors was identified starting with the HTS hit 1. After SAR investigation based on a prospective consideration of two drug-likeness metrics, ligand efficiency (LE) and fraction of sp(3) carbon atoms (Fsp(3)), significant improvement of metabolic stability as well as reduction of CYP inhibition was observed, which finally led to discovery of a selective and orally efficacious RORγ inhibitor 3z.

Abstract
It is difficult to treat infected implants of the hip joints. Such treatment involves immeasurable physical and psychological suffering of the patients. We used antibiotic-impregnated cement spacers in 17 cases of infection after total hip arthroplasty and bipolar arthroplasty with good clinical results. We thoroughly removed any foreign material and formed an antibiotic-impregnated cement spacer into a similar shape as that of the implants. A cement spacer enables high-concentration antibiotics to act on infected sites. Also, it can prevent leg length discrepancy and atrophy of bones or muscles. Although cement spacers have been reported to have problems regarding shape and strength, we achieved good results with a cement spacer mold in the present study. No recurring infection has been found at a mean follow-up period of 3 years and 2 months.

Abstract
Involvement of cannabinoid CB2 receptors in the IgE-mediated cutaneous reaction was investigated. Epicutaneous challenge with 2,4-dinitrofluorobenzene caused a triphasic swelling in the ear of BALB/c and C57BL/6 mice passively sensitized with anti-dinitrophenol IgE. Peak responses of the ear swelling appeared at 1 h, 24 h, and 8 days after the challenge in both strains of mice. In contrast, cannabinoid CB2 receptor-deficient mice failed to exhibit the obvious triphasic ear swelling observed in wild-type mice. Oral administration of cannabinoid CB2 receptor antagonist/inverse agonists [N-(benzo[1,3]dioxol-5-ylmethyl)-7-methoxy-2-oxo-8-pentyloxy-1,2-dihydroquinoline-3-carboxamide] (JTE-907) and {N-[(1S)-endo-1,3,3-trimethylbicyclo[2,2,1]heptan-2yl]5-(4-chloro-3-methyl-phenyl)-1-(4-methylbenzyl)pyrazole-3-carboxamide} (SR144528) at doses of 0.1-10 mg/kg significantly and dose-dependently suppressed all three phases of ear swelling in BALB/c mice. Interestingly, epicutaneous treatment with an ether-linked analogue of endogenous cannabinoids, 2-arachidonoylglycerol, caused an ear swelling that could be detected at 1 h, 24 h, and 8 days after treatment of both BALB/c and C57BL/6 mice. These results suggest that cannabinoid CB2 receptors are involved in induction of the triphasic cutaneous reaction mediated by IgE, and that cannabinoid CB2 receptor antagonist/inverse agonists may serve as anti-allergic agents in the treatment of allergic dermatitis.

Abstract
Involvement of cannabinoid CB(2) receptor and effect of cannabinoid CB(2) receptor antagonist/inverse agonists on cutaneous inflammation were investigated. Mice ears topically exposed to an ether-linked analogue of 2-arachidonoylglycerol (2-AG-E) or selective cannabinoid CB(2) receptor agonist, {4-[4-(1,1-dimethylheptyl)-2,6-dimethoxy-phenyl]-6.6-dimethyl-bicyclo[3.1.1]hept-2-en-2-yl}-methanol (HU-308), had early and late ear swelling (0--24 h and 1--8 days after exposure, respectively). Both types of responses induced by 2-AG-E were significantly suppressed by oral administration of cannabinoid CB(2) receptor antagonist/inverse agonists, [N-(benzo[1,3]dioxol-5-ylmethyl)-7-methoxy-2-oxo-8-pentyloxy-1,2-dihydroquinoline-3-carboxamide] (JTE-907) and {N-[(1S)-endo-1,3,3-trimethylbicyclo[2.2.1]heptan-2 yl]5-(4-chloro-3-methyl-phenyl)-1-(4-methylbenzyl)pyrazole-3-carboxamide}} (SR 144528). In contrast, JTE-907 did not affect arachidonic acid-induced swelling. Orally administered JTE-907 (0.1-10 mg/kg) and SR 144528 (1 mg/kg) also produced significant inhibition of dinitrofluorobenzene-induced ear swelling, with increased cannabinoid CB(2) receptor mRNA expression observed in the inflamed ear. These results suggest that cannabinoid CB(2) receptor is partially involved in local inflammatory responses and cannabinoid CB(2) receptor antagonist/inverse agonist has beneficial effects on ear swelling.

Abstract
The utilisation of antitumour T cells induced by cancer vaccination with HER-2 peptides or antibodies (Herceptin) against HER-2, as immunotherapy for oesophageal cancer, is a novel and attractive approach. It is important to clarify the frequencies of HER-2 expression and gene amplification in patients with oesophageal squamous cell carcinoma (SCC) and to evaluate the relationship between HER-2 status and HLA haplotype, since the candidates for HER-2 peptide-based vaccination are restricted to a certain HLA haplotype. We determined the frequency of HER-2 expression using the HercepTest for immunohistochemistry and HER-2 gene amplification by fluorescence in situ hybridisation (FISH) assay in oesophageal SCC (n=66). HER-2-positive tumours (1+/2+/3+) analysed by a HercepTest were observed in 30.3% of all the patients and HER-2 gene amplification evaluated by FISH was observed in 11.0% of all the patients, in which all HercepTest (3+) tumours were found to have gene amplification and three of six moderately positive (2+) tumours showed gene amplification. Furthermore, HER-2-positive cells were present more diffusely and were larger within each tumour in the patients who were HercepTest 3+ than those who were HercepTest 1+. Moreover, the survival rate in HER-2-positive group was significantly worse than that in HER-2-negative group. Also, the survival rate in the patients with HER-2 gene amplification was significantly worse than that without HER-2 gene amplification. In addition, oesophageal SCC patients with both HLA-A24-positive and HER-2-positive tumours (1+/2+/3+) accounted for 26% of these cases, and both HLA-A2- and HER-2-positive tumours accounted for 18% of them.

Abstract
The effects of a newly synthesized compound, 6-acetoamido-1-acetyl-1-indazole (TAS-3-124), on autoimmune diseases were studied. We used animal models of collagen-induced arthritis (CIA) in mice and experimental autoimmune encephalomyelitis (EAE) in rats to evaluate the efficacy of TAS-3-124. TAS-3-124 at doses of 100 and 300 mg/kg p.o. inhibited the development of CIA, decreasing the swelling of fore- and hind-limbs and bone destruction in knee joints. This agent also suppressed the delayed type hypersensitivity reaction (DTH) against type II collagen. These effects were confirmed by histopathological examination and measurement of the expression of mRNA of proinflammatory cytokines in the knee joint. In addition, TAS-3-124 at a dose of 300 mg/kg inhibited the development of EAE and the DTH to myelin basic protein (MBP) in rats. Moreover, TAS-3-124 inhibited the production of proinflammatory cytokines including interleukin (IL)-1beta, tumor necrosis factor (TNF)-alpha and IL-6 but not T cell derived cytokines in mice. These demonstrate the efficacy of TAS-3-124 against experimental autoimmune disease, probably due to the suppression of the production of proinflammatory cytokines in the pathological lesion.

Abstract
It is difficult to treat an infected implant of the hip joints, as it requires long-term treatment and eventually may lead to amputation or arthrodesis, involving immeasurable physical and psychological suffering for the patient. We utilized antibiotic-impregnated cement spacers for 17 infections after total hip arthroplasty and bipolar arthroplasty with good clinical results. We thoroughly removed any foreign material and formed an antibiotic-impregnated cement spacer into a shape similar to that of the implants. This enabled high-concentration antibiotics to act on the infected sites. It also can prevent leg-length discrepancy and atrophy of bones or muscles. Although cement spacers have been reported to have problems regarding shape and strength, we achieved good results with cement spacer molds in the present study. All revision surgeries were performed using a two-stage procedure. No infection has recurred at a mean follow-up of 3 years 2 months.

Abstract
Two cases of Werner's syndrome are reported. The first case is that of a man with grey hair since his 20s, and alopecia since aged about 50 years. At the age of 53 years, Werner's syndrome was diagnosed, along with a malignant soft tissue tumour of the hand. The patient underwent ray amputation for the tumour. The subsequent histopathological diagnosis was synovial cell sarcoma, and the patient died of lung metastasis at 15 weeks postsurgery. The second case is that of a woman diagnosed with diabetes mellitus when aged 34 years. At 39 years, a bilateral cataract was diagnosed and at 40 years, diabetic gangrene of the left calcaneal region and calcaneal osteomyelitis necessitated left below-knee amputation. The incidence of Werner's syndrome in Japan is extremely high (1000 of the around 1300 cases reported worldwide) compared to other countries. Most patients develop malignant tumour or arteriosclerosis, the most important complications of this syndrome. The average life expectancy for patients with Werner's syndrome is 46 years. The incidence of epithelial cancer and mesenchymal sarcoma is 10 times that of the general population. The onset of symptoms of Werner's syndrome generally precedes any later symptoms of associated conditions, such as malignant tumour. Therefore, early recognition of Werner's syndrome is important to assist identification of malignant tumours at an early stage in this patient group.

Abstract
The effect of 4-[3,5-bis(trimethylsilyl)benzamido] benzoic acid (TAC-101), one of the synthetic retinoids, on collagen-induced arthritis (CIA) in mice and experimental autoimmune encephalomyelitis (EAE) in rats was studied. TAC-101 at doses of 5 and 20 mg/kg clearly inhibited the development of CIA in terms of the swelling of fore- and hind-limbs and bone destruction in knee joints. TAC-101 also suppressed the production of anti-type II collagen (CII) IgG antibody and delayed-type hypersensitivity (DTH) against CII. In addition, TAC-101 delayed the onset and development of EAE but did not affect the maximum symptom of EAE in rats. The elevation of serum antimyelin basic protein (MBP) antibody and DTH to MBP on day 13 clearly suppressed by TAC-101 in EAE rats. Moreover, TAC-101 inhibited the IL-1beta-induced PGE(2) production by MG-63 cells, human osteoblast-like cells, through the suppression of cyclooxygenase II mRNA expression. These findings suggest that TAC-101 inhibits CIA in mice and EAE in rats due to the suppression of immune response to auto-antigen and the production of PGE(2).

Abstract
Acute thrombosis of an abdominal aortic aneurysm (AAA) is a surgical emergency. Only 44 cases have been reported in the literature. The mechanism of the thrombosis has not been delineated. The proposed etiologies include propagation of thrombus from distal artery occlusion, cardiac thromboembolism, and dislodgment of a mural thrombus. Patients often present bilateral lower extremity ischemia, mimicking a saddle embolism. Systemic heparinization immediately after diagnosis and prompt surgical revascularization can reduce the mortality rate. The authors present a patient with sudden thrombosis of an AAA who was successfully treated with an axillobifemoral bypass graft. All published cases of thrombosed AAAs are analyzed.

Abstract
CD8+ T cells in FIV-infected cats inhibit feline immunodeficiency virus (FIV) replication by producing a soluble factor(s). In the present study, four SPF cats were experimentally infected with FIV. The period during which the anti-FIV activity of CD8+ T cells became detectable was investigated, and the presence or absence of this activity in the lymph nodes and spleen was examined. Furthermore, we investigated which step(s) of the FIV replication cycle are affected by this antiviral activity. This antiviral activity became detectable five weeks after FIV infection in early cases, and it was simultaneous with or one week after the induction of humoral immunity. All cats having CD8+ T cells with anti-FIV activity in the peripheral blood also possessed CD8+ T cells with anti-FIV activity in the lymph nodes. In contrast, CD8+ T cells from the spleens of some, but not all cats showed anti-FIV activity. CD8+ T cell-depleted peripheral blood mononuclear cells were cultured and reconstituted with CD8+ T cells on day 12 of culture after confirming FIV replication. The number of FIV proviral DNA copies in the cells did not change, but the amount of FIV p24 antigen production in the culture supernatant and the number of FIV mRNA copies in the cells decreased. These findings suggested that CD8+ T cell anti-FIV activity acts at the level of FIV mRNA synthesis from the FIV proviral DNA, inhibiting FIV replication by a non-cytolytic mechanism.

Abstract
We report an unusual adult case of aneurysm associated with the ductus arteriosus. A 67-year-old female, who suffered recurrent nerve palsy, was diagnosed as having an aneurysm of the ductus arteriosus. The aneurysm, located in the medial aspect of the aortic ischimus and projected toward the pulmonary artery, was successfully repaired using a Dacron patch. A pathologic review of the aneurysm revealed the degeneration of the aortic media.

Abstract
Coronary artery fistula (CAF) is an uncommon congenital anomaly. Bilateral CAFs, arising from both right and left coronary arteries are rare. Myocardial infarction is by far a less frequent complication of CAF than angina pectoris. Ligation of CAF and coronary artery bypass graft were performed in the treatment of coronary artery stenosis with CAF.

Abstract
Behçet's disease is a systemic disease characterized by oral aphta, genital ulcer, and ocular lesion. Arterial involvement is an uncommon complication of Behçet's disease, and it most frequently affects the abdominal aorta followed by the femoral artery and the pulmonary artery. Coronary lesions in Behçet's disease have been little reported in the literature. In this communication, we present a case with coronary artery stenosis and with subsequently developed supra-renal abdominal aortic aneurysm. The coronary lesions were revasculized with gastroepiploic artery, right internal mammary artery, and saphenous vein graft. Abdominal aortic repair was performed with partial cardiopulmonary stand by, because of the risk of coronary ischemia during the cross clamp including the celiac artery. To our knowledge, this is the first report of successful repair of combined lesions of the coronary and the abdominal aorta in a patient with Behçet's disease.

Abstract
PURPOSE Autoimmunity has been proposed to play a role in the pathogenesis of the abdominal aortic aneurysm (AAA). Several autoimmune diseases are associated with specific HLA DR alleles. These experiments were carried out to determine whether the same HLA DR types that have been reported to be associated with AAA in a mixed North American population are similarly associated with AAA in a more homogeneous group of patients in Japan. METHOD HLA DR typing was performed by a serologic method on samples of peripheral blood of patients with nonspecific infrarenal AAA in Nagasaki University Hospital in Japan. The frequencies of HLA DR antigens were compared with those of volunteers approximately matched for age and sex from the same referral area. RESULTS HLA DR haplotypes were determined in 46 Japanese patients with AAA and in 50 patients in a control group. The HLA-DR2(15) antigen was observed in 27 (58.7%) patients (29 alleles 31.5%) with AAA and in 14 (28%) subjects (16 alleles 26.0%) in the control group (p < 0.005). CONCLUSIONS The data suggest that HLA-DR2(15) has an important role as a genetic risk factor for AAA in Japanese patients, as previously reported in a mixed North American population.

Abstract
Norepinephrine (NE) is one of the most potent positive inotropic drugs available for the treatment of low-output state following open-heart surgery. However, its inotropic effect is often masked by a significant increase of peripheral vascular resistance due to marked vasoconstriction. The purpose of the present study was to investigate whether the use of nicardipine (Nc) and phentolamine (Ph) in combination with NE could ameliorate the adverse vasoconstrictive action of NE. A low-output-state (LOS) model was produced by global myocardial ischemia due to electrically induced intermittent ventricular fibrillations in open-chest dogs. Twenty-eight dogs were divided into 6 groups according to the drugs infused after producing LOS. In the control group, hemodynamic changes similar to the clinical low-output state were observed, e.g., a decrease in cardiac output (CO) and left ventricular dp/dt, and an increase in the systemic vascular resistance (SVR). The use of NE alone produced marked increases in the systemic arterial pressure (SAP), heart rate, and SVR, with a slight increase in CO. The infusion of Nc alone produced decreases in SVR and SAP with a slight increase in CO. The concomitant infusion of NE and Nc produced increases in SV and CO, and decreases in SAP and SVR. The infusion of Ph alone produced no significant hemodynamic changes. The combined use of NE and Ph produced increases in CO, SAP and heart rate, but not to a significant extent. These results suggest that there are major advantages in the concomitant use of NE and Nc for the control of LOS.

Abstract
A 57-year-old female with valvular heart disease and chronic idiopathic thrombocytopenic purpura (ITP) underwent successful open-heart surgery. Preoperative administration of steroids and high-dose gamma-globulin increased the platelet count from 3 x 10(4)/microgram at admission to 10 x 10(4)/microgram before the operation. Splenectomy followed by mitral valve replacement (SJM 27M) were performed simultaneously. No platelet transfusion needed during and after the operation owing to rapid increase in platelets that would occur following splenectomy. The postoperative course was uneventful. The present simultaneous splenectomy and open-heart operation appears to be a safe and effective procedure for minimizing perioperative blood loss in patients with ITP and heart disease.

Abstract
Since November 1989, low-density lipoprotein apheresis has been applied to patients with intractable hyperlipidaemia following bypass grafting for chronic arterial occlusion of the lower extremities. The treatment group comprised six patients (four men, two women) with arteriosclerosis obliterans. In five patients, the ankle pressure index deteriorated and intermittent claudication recurred due to atherosclerotic progression. Results of low-density lipoprotein apheresis were dramatic; the deteriorated ankle pressure index and intermittent claudication improved significantly after several applications of low-density lipoprotein apheresis. Significant angiographic improvement was obtained in two patients. It is concluded that low-density lipoprotein apheresis appears to be an efficient method to preserve graft patency and treat postoperative patients with deteriorated ankle pressure index.

Abstract
The effects of Na+ and Ca2+ concentrations in the reperfusate on post-ischemic myocardial recovery were examined. Also, the myocardial protective effects of amiloride, an inhibitor of the Na+/Ca2+ and Na+/H+ exchange systems, added to cardioplegic solutions were assessed, using an isolated working rat heart perfusion system. Global myocardial ischemia was induced by 30-min normothermic cardioplegic arrest, using St. Thomas' solution. The concentration of Na+ in the reperfusate varied, stepwise, from 75 to 145 mM/l, and that of Ca2+, from 0.1 to 2.5 mM/l. In this study post-ischemic functional recovery was best at 110mM/l Na+ and 1.2-1.8 mM/l Ca2+ in the reperfusate. A significantly greater post-ischemic functional recovery and a lower creatine kinase release were observed when amiloride was added to the cardioplegic solution. Ca2+ overload via Na+/Ca2+ and Na+/H+ exchange systems would, thus, appear to be due, at least in part, to post-ischemic reperfusion injury.

Abstract
The best configuration for holographic optical heads for compact disk players is discussed from the viewpoint of considering the misalignment allowance for head components. Focus-error and trackingerror signals of the proposed head configurations are simulated with a ray-tracing method and by using optical cross transfer function theory. The misalignment allowance for the head components, such as the objective lens, the holographic optical element, and the photodetector, are calculated for several configurations. The misalignment allowance is found to increase greatly when the holographic optical element is placed in close proximity to the objective lens and then when this assembly is moved as a unit.

Abstract
Butylated hydroxytoluene has been known to protect spermatozoa from cold shock injury. To determine whether such protective action is a common property of aromatic compounds, the effect of 14 hydrophobic and 2 hydrophilic aromatic compounds on the protection of boar spermatozoa from cold shock was investigated. The majority of the hydrophobic compounds tested provided protection; the hydrophilic compounds were ineffective. Of the aromatic compounds tested, naphthalene was most effective in reducing the effect of cold shock on motility and acrosomal integrity of boar spermatozoa.

Abstract
The influence of melatonin on reproductive behavior was examined by administering it to pinealectomized male rats for 30 consecutive days. After the 30-d administration of melatonin or vehicle, each male rat was introduced into a female rat's cage on the day of proestrus and allowed to mate overnight. All rats administered the vehicle and the pinealectomized rats copulated; five of the twelve melatonin (8.0 mg/kg)-treated rats did not copulate. These findings suggest that melatonin inhibits the reproductive behavior of male rats.

Abstract
The relationship between zinc sulfate turbidity test (ZTT and thymol turbidity test (TTT), and IgG subclasses, especially IgG1 and IgG2, was studied. Serum colloidal reactions of specimens from patients with IgG-myeloma usually show abnormally high values in ZTT and low values in TTT. But in some cases, values in ZTT and TTT are both low, and in a few cases both values are abnormally high. In order to see the reason why IgG-myelomas are classified into these three groups according to serum colloidal reactions. IgG subclasses of monoclonal proteins (MPs) isolated by zone electrophoresis were determined by immunodiffusion with anti IgG-subclasses. Results revealed that IgG1-myeloma showed high ZTT and low TTT and IgG2-myeloma showed low ZTT and TTT. Only two out of our 29 cases with IgG-myeloma showed high ZTT and TTT. MP from one of them belonged to IgG1-kappa and that from the other to IgG2-lambda. We checked the relationship between turbidity tests and electrophoretic mobility of MP and also that between these tests and L-chains' type of MP, but did not find any relationship between them. These findings suggest that IgG1 innately reacts with ZTT but not with TTT, while IgG2 does not react with any of these tests. MP from cases showing high values in both ZTT and TTT may have a special idiotype.

Abstract
The serum from a 78-year-old male (SY) with abdominal aneurysm was shown to contain monoclonal protein (MP) of IgG. Immunoelectrophoresis (IEP) and immunofixation electrophoresis (IFE) of SY serum revealed MP reacted with both of anti kappa and anti lambda antisera. To see whether the monoclonal IgG molecule possesses both types of light chains, an attempt to separate MPs isolated by zone electrophoresis was made by affinity chromatography using anti kappa and anti lambda Sepharose 4 B conjugates. Immunodiffusion (ID) of these separated MPs showed that kappa type of MP (MP-kappa) was IgG1, while lambda type of MP (MP-lambda) was IgG3. For preparation of anti-idiotype antibodies (Aid) against MP-lambda, antisera against MP-lambda raised in rabbits by immunization with affinity-chromatographic purified MP-lambda was absorbed with solid phase normal human serum. ID and IFE of these MPs (original MP, MP-lambda and MP-kappa) revealed MP-kappa did not react with Aid, suggesting idiotype of MP-kappa was different from that of MP-lambda. These results indicate that two types of MPs derived from different B cell clones happen to have same mobility electrophoretically.
