Abstract
Prolactin (PRL) levels in the cerebrospinal fluid (CSF) and plasma of 25 patients with sellar and suprasellar tumors, i.e. 5 of PRL secreting adenoma, 5 of GH secreting adenoma, 7 of so-called non-functioning pituitary adenoma, 5 of tuberculum sellae meningioma and 3 of craniopharyngioma, were studied in relation to the size of suprasellar extension measured by our own method on pneumoencephalograms. Plasma and CSF samples were obtained simultaneously at the time of lumbar puncture for pneumoencephalography. 1) Five patients of PRL secreting adenoma, whose plasma PRL levels ranged from 530 to 4,000 ng/ml, showed high PRL levels over 50 ng/ml in the CSF. On the contrary, 20 patients of the other tumors, whose plasma PRL levels were lower than 30 ng/ml, showed low PRL levels in th4 CSF, being below the sensitivity limit in the majority. 2) In 3 out of 5 PRL secreting adenomas, the PRL level in the CSF was higher than the plasma level and they showed a fairly large extrasellar extension. However in the remaining 2 the PRL level in the CSF was lower than a tenth of that in the plasma, and these revealed relatively small suprasellar extension. From these facts the presence of PRL at a high level in the CSF seems to be specific in the PRL secreting adenomas, and there seems to be a relationship between the CSF-plasma ratio of PRL level and the extrasellar extension in these cases.

Abstract
Cytotoxicity of lymphocytes against allogeneic target cells of a bronchogenic squamous cell carcinoma was examined by a microcytotoxicity test in lung cancer patients after the various kinds of anticancer treatment. Cytotoxicity in untreated cases at stages I, II, and III was higher than the range of controls, but cytotoxicity in those at stage IV decreased to the range of controls. Tumor resection augmented cytotoxicity in patients at stages II and III, when the assays were carried out 3 weeks after the operation. Local irradiation of tumors augmented cytotoxicity in patients at stages II, III, and IV, when the assays were carried out 1 week after the last irradiation. Immunotherapy with BCG cell-wall skeleton augmented cytotoxicity to a marked degree in patients at stages I, II, III, and IV, when the assays were carried out after 4 months of a continuous treatment. The microcytotoxicity test may be useful for estimating the reactivity of lymphocytes in lung cancer patients in various situations.

Abstract
A 21-year-old man had progressive symmetric, distal muscle atrophy and weakness, as well as spasticity of the limbs. Histologic examination of the sural nerve disclosed swollen axons containing membranous tubular profiles, ring tubules, large mitochondria with abnormal cristae, and glycogen like granules. Peripheral sensory nerve fibers also were affected. The pathologic features of the peripheral nerves were similar to those of infantile neuroaxonal dystrophy. Sural nerve biopsy may be useful in the study of pathologic processes in spastic paraplegia.

Abstract
Postoperative angiocardiographic findings were examined in eight patients whose pulmonary artery was reconstructed using an aortic or pulmonary homograft with valve. Apparent dilatation of the outflow tract of the right ventricle was seen in three patients. Only four showed valve mobility, with function judged almost normal in two of them. Calcification in a valve was not seen. The pulmonary trunk showed three directional patters, and stenosis was clearly observed in two cases. calcification of the pulmonary trunk was seen in only one case. The most difficult problem in the reconstruction of the pulmonary artery is the high incidence of pulmonary stenosis.

Abstract
Effect of BCG cell-wall skeleton (BCG-CWS) on the recovery of responsiveness of lymphocytes and the survival period was studied in patients with lung cancer. (a) Responsiveness of lymphocytes as demonstrated by proliferative response to phytohemagglutinin (PHA) or microcytotoxicity test with cultured cells of a bronchogenic carcinoma was depressed in the patients at later stages of cancer and it was restored by treatment with BCG-CWS in many of such patients. (b) Survival period of the patients at later stages such as III or IV was prolonged by treatment with BCG-CWS. Such an effect was detected even in the patients with carcinomatous pleuritis. (c) A close correlation was found between the reactivity such as PHA response or cytotoxicity and clinical course of the patients given BCG-CWS. Assay system with PHA response and microcytotoxicity test appears to be reliable in anticipating the prognosis and in following clinical course after the BCG-CWS treatment.

Abstract
Using the capsular polysaccharide of Klebsiella pneumoniae (CPS-K) as a polyclonal B-cell activator (PBA) and sheep red blood cells (SRBC) as a T cell-dependent antigen, we compared the ability of PBA and antigen to differentiate (generate antibody-forming cells, AFC) and proliferate (generate immunological memory) virgin B cells and B memory cells. In vitro CPS-K induced the differentiation of IgM virgin B cells, IgM B memory cells and IgG B memory cells to AFC, as well as or better than SRBC. The differentiation of B memory cells to AFC by CPS-K did not require the participation of macrophages or T cells, whereas the action of SRBC depended strictly upon the helper actions of these cells. The responsiveness to CPS-K and SRBC of normal and antigen-primed spleen cells as judged by anti-SRBC PFC responses in vitro was markedly decreased after stimulation of virgin B cells and B memory cells in vivo by CPS-K injection into normal or primed mice but greatly increased after the injection of SRBC. The decrease in the responsiveness to CPS-K of spleen cells from mice treated with CPS-K appeared principally due to exhaustion of the functions of B cells and B memory cells. From the present data it has been concluded that the signals required for the differentiation and proliferation of B cells of B memory cells are different from each other, the signal for differentiation being provided by either antigen (SRBC) or PBA (CPS-K), while the signal for proliferation only by antigen.

Abstract
Ultrastructural study of the biopsied sural nerve in a case of infantile neuroaxonal dystrophy was made. The characteristic change in the ballooned axons is an accumulation of membranous profiles associated with mitochondria, glycogen like granules, dense bodies, vesicles and electron lucent material. The membranous profile is classified into three morphological types and discussed on each of them. Probably tubulomembranous profile of the first type is most common and may be cardinal deposit in this condition. These membranous structures of various types might be, however, only different manifestations occurring on the same morbid process. Enormous amount of glycogen like granules and mitochondria might be related to the metabolic derangement of carbohydrate in the ballooned axons. Electron lucent material we observed was not described in the previous papers on this condition. We added one more example showing that nerve biopsy is helpful to confirm the diagnosis in infantile neuroaxonal dystrophy.

Abstract
Adjuvant and antitumor activities of CWS prepared from cells of mycobacteria, nocardia, and corynebacteria were examined. Oil-attached CWS of M. bovis BCG (BCG-CWS) stimulated the generation of cell-mediated cytotoxic effector cells in mice. Tumor growth was suppressed in mice inoculated intradermally with a mixture of oil-attached CWS and living tumor cells. Systemic and specific tumor immunity was demonstrated in mice in which tumor growth was suppressed. Tumor growth was also suppressed by oil-attached CWS of BCG or N. rubra in autochthonous autografts of spontaneous mammary adenocarcinoma and methylcholanthrene-induced fibrosarcoma in mice. The intravenous injection of oil-attached BCG-CWS prevents the appearance of lung cancer in rabbits by the instillation of chemical carcinogens. It was also shown that treatment with oil-attached BCG-CWS was able to elevate the immunologically depressed state of tumor-bearing mice to a normal level, as determined by a cell-mediated cytotoxicity assay that empolyed chromium release as the standard. Preliminary results suggest that oil-attached BCG-CWS is useful as an immunotherapeutic agent for both lung cancer and for malignant melanoma, leukemia, Hodgkin's disease, and other neoplastic diseases and that this agent operates without any significant complications.

Abstract
The neutral fraction (neutral CPS-K) of Klebsiella pneumoniae capsular polysaccharide (CPS-K) from type 1, Kasuya strain, has already been reported as the active substance responsible for the strong adjuvant effect of CPS-K. The present results demonstrate that neutral CPS-K exhibits further common biological activities with lipopolysaccharide (LPS) isolated from Salmonella enteritidis. The intensity of the lethality in mice of neutral CPS-K by the intraperitoneal route is very similar to that of LPS. Its lethality for mice by the intravenous (i.v.) route is significantly stronger than that of LPS, because the degree of increase in the sensitivity to their lethality by i.v. challenge is smaller for LPS than for neutral CPS-K. The intensity of the pyrogenicity of neutral CPS-K in rabbits is approximately one-tenth of that of LPS as judged by the minimal pyrogenic doses and fever indices. The skin-preparatory potency of neutral CPS-K for the dermal Shwartzman phenomenon in rabbits is also approximately one-tenth of that of LPS compared on the basis of the minimal skin-preparatory doses. When injected i.v., neutral CPS-K exhibits a provocative effect on hemorrhagic reactions in skin sites prepared with neutral CPS-K or LPS.

Abstract
A drilling at 500 000 R.P.M. with a dental high speed turbine was made either to a tissue culture bottle or to a test tube, in which mouse L fibroblasts were grown for 2 days with YLH medium supplemented with 10% bovine serum, in order to examine the effects of high speed drilling to the cells in vitro, Experiments were carried out with the following three conditions; (1) Drilling of outer surface of the glasswares at the inner surface on which the cells were attached, with a water coolant, (2) Drilling of the same place without a water coolant, and (3) Drilling of a remote area of the glasswares where no cells were grown. The last experimental condition permitted to give a sole effect of vibration accompanied with the drilling. Rates of cell multiplication and morphological observation were obtained on 2 days and 5 days after the glasswares were drilled. Rates of cell multiplication showed no change between the experimental conditions and control. This means that heat generation, vibration and/or their compound effects during drilling did not deter cells from growing. Morphological change of the cells due to the drilling was parallel to the results of cell multiplication except the drilling without a water coolant. When drilled without a water coolant, the cells around the drilled area was deteriorated and died after 24 hours. However, most of the cells away from the drilled area were not affected. The present results can not directly apply to the drilling in dental clinic, since in vivo condition has more complicated situation, some of which can not be simulated in in vitro environment. However, the in vitro results can surely be important information in resolving drilling effects in vivo.

Abstract
Twenty-seven patients with juvenile nonprogressive muscular atrophy localized in the hand and forearm were analyzed. The clinical characteristics were juvenile male occurrence, insidious onset, specific distribution of localized muscular atrophy and a stationary course. On electromyography, denervation voltage (or giant NMU) is found in the atrophied muscles and sometimes in contralateral nonatrophied ones. Sensory disturbance was not remarkable. Although the etiological factor was not known, strenuous exercise of arms in sports was noted frequently in the history.

Abstract
A new method was used for selective measurement of lipoprotein lipase and hepatic lipase in human postheparin plasma. Hepatic lipase was assayed in 1.0 M NaCl withour addition of serum, and the activity of lipoprotein lipase was determined in 0.1 M NaCl after immunoprecipitation of hepatic lipase with specific antiserum. The activity of both these enzymes and the total lipolytic activity were measured in plasma samples taken during a 4-h infusion of heparin. Each of the activities was related to basal serum triglyceride concentration and to the fractional removal constant (K) of Intralipid in 13 obese subjects before and after prolonged fasting. During a normal isocaloric diet the lipolytic activities showed a biphasic response to heparin infusion in all subjects. A peak activity was reached within 30 minutes ("early response") and thereafter the lipase activities decreased to a constant level maintained during the rest of the heparin infusion ("late response"). The early response of lipoprotein lipase showed a significant inverse correlation with the basal serum triglyceride level (r = -0.85) and a significant positive correlation with the fractional removal rate of Intralipid (r = 0.84). The late response of lipoprotein lipase was not related to either of these parameters. The early response of hepatic lipase was not correlated with basal triglyceride concentration or Intralipid removal, whereas the late response of this enzyme showed a significant negative correlation with the removal rate of Intralipid (r = -0.82). After fasting for several days the acute response of all lipolytic activities to heparin was markedly decreased or totally abolished, but the magnitude of the late response was similar to that seen in the fed state. The fractional removal rate of Intralipid was slightly increased by starvation. All correlations between postheparin plasma lipases and serum triglyceride concentration and removal disappeared in fasting subjects. It is concluded that the rapidly releasable lipoprotein lipase probably reflects the activity of the tissue enzyme(s) which is responsible for the primary removal of very low density lipoprotein (VLDL) triglycerides and chylomicrons. It is probable that this component of the postheparin plasma lipolytic activity is derived from the endothelial lipoprotein lipase pool. This enzyme plays a key role in the efflux of plasma triglycerides under normal conditions, and it is thus one determinant of plasma triglyceride level. Prolonged fasting obviously changes the triglyceride removal sites and mechanism but does not impair the removal efficiency.

Abstract
The diagnostic criteria, natural history, nerve conduction characteristics, pathology, laboratory features, and efficacy of corticosteroid treatment have been evaluated personally in 53 patients with chronic inflammatory polyradiculoneuropathy (CIP) who were followed up for an average of about 7.5 years. These were patients whose monophasic neurologic deficit had not crested by 6 months, patients with recurrences, and patients with a steady or stepwise progression. The typical features of CIP include absence of an associated disease, frequent history of preceding infection or receipt of foreign protein, and tendency to involve cranial, truncal, and proximal as well as distal limb structures and to have diffusely slow conduction velocity of peripheral nerves. The most marked slowing is often very proximal. The pathologic features include serous edema, mononuclear cell infiltrates (especially in perivascular areas, but without evidence of vasculitis), macrophage-induced segmental demyelination, and hypertrophic neuritis. If our patients are representative, complete recovery occurs only infrequently; about 60% of patients are able to be ambulatory and work, 25% become confined to a wheelchair or become bedridden, and approximately 10% die from their disease. Although the bulk of the pathologic changes affect spinal roots and proximal nerves, the brain and spinal cord may be involved also. Degeneration into linear rows of myelin ovoids is the predominant type of myelinated fiber degeneration of the sural nerve at the ankle.

Abstract
An 8-year-old girl had progressive muscle weakness and a unique posture of the lower limbs, areflexia, distal sensory impairment, and remarkably kinky hair. Histologic examination of the sural nerve showed giant axons filled with neurofilamentous masses. The clinical and histologic findings resembled those of recent cases reported as "giant axonal neuropathy." Our patient's precocious puberty, Babinski's sign, and electroencephalographic abnormalities suggested central nervous system involvement. Two cases previously reported and the present one appear to represent a new clinical entity that affects the central and the peripheral nervous system.

Abstract
A comparison of the results of machine and human information retrieval using MEDLARS and the printed Index Medicus indicates that at present neither method is entirely satisfactory for exhaustive literature searches. The advantages and disadvantages of machine and manual search methods are discussed, and solutions to some of the problems are suggested.
