Abstract
Establishment of a mouse T hybrid cell line secreting suppressor factor(s) specific for the IgE antibody response is described. Fusion was made with polyethyleneglycol between AKR-derived T lymphoma cells (BW5147) and T cells from mice sensitized with DNP-Mycobacterium. Treatment of spleen cells with nondialyzable factor(s) in the culture supernatants of the T cell hybrid clone, 26-M10, showed a suppressive effect on IgE formation but not on IgG formation in adoptive transfer experiments. The suppressive effect was exerted through inactivation of normal or antigen-primed B cells responsible for IgE formation. It was also shown by direct cytotoxic test that the hybrid cells expressed H-2 and Thy-1 antigens derived from both parental cells on their surface. Karyotype analysis of the hybrid cells revealed that the number of chromosomes was less than the sum of the two parental cells' and the average was 50 (45 to 55). Although the 26-M10 hybrid cells lost the ability to secrete active suppressive factor(s) into culture medium 21 weeks after hybridization when the number of chromosomes in most of the cells was less than 41, recloning of the 26-M10 cells successfully recovered active suppressive clones.

Abstract
Broadcillin 'Banyu', which contains an equal amount of ampicillin and oxacillin was given intravenously to children with acute bacterial infections and the following results were obtained. 1. Patients were 55 children with the following bacterial infections; respiratory tract infections (8 cases), pneumonia (34), sepsis (1), meningitis (1), cutaneous and subcutaneous suppurative inflammation (5), osteomyelitis (1), urinary tract infection (2), enteritis (1), and chemoprophylaxis (2). They ranged in age from newborns to 8 year old, but most of them were infants. In the majority of the patients, broadcillin 'Banyu' was administered 50 approximately 150 mg/day in three to four equally divided doses by one shot-injection or by a continuous drip infusion for a period of 2 approximately 10 days. The overall efficacy rate was 88.7% in 53 cases after two cases of chemoprophylaxis were excluded, i.e., excellent in 28, good in 19 and failure in 6: excellent in 4 and good in 4 in 8 cases of respiratory tract infections; excellent in 20, good in 11 and failure in 3 in 34 cases of pneumonia (an efficacy rate 91.2%); failure in sepsis and meningitis: excellent in 2 and good in 3 in 5 cases of cutaneous and subcutaneous suppurative inflammation; excellent in osteomyelitis; excellent in 1 and good in 1 of 2 cases of urinary tract infection; failure in enteritis. 2. Adverse reactions were noted on 10 occasions in 9 cases (16.4%), including 1 case of skin eruption, 1 case of eosinophilia, 5 cases of slight elevation of GOT, 1 case of slight elevation of GPT and 2 cases of slight elevation of BUN. 3. Based on the above results, it was concluded that clinical effect of broadcillin 'Banyu' by an intravenous administration is comparable to its intramuscular route and that safety of intravenous usage seems to be verified as long as the above described dosage is followed.

Abstract
Two patients with chronic neurogenic quadriceps amyotrophy are reported. A 61-year-old woman had symmetrical wasting and weakness of the quadriceps femoris of eight years' duration. A biopsy revealed neuropathic changes, and electromyograms showed neurogenic as well as myopathic patterns in the quadriceps and other muscles. A 29-year-old woman had long-standing wasting limited to the quadriceps and hip muscles. EMG and biopsy were compatible with neurogenic atrophy. She had a brother suffering from a more widespread and severe form of the disease. These cases suggest that chronic neurogenic quadriceps amyotrophy is a forme fruste of Kugelberg-Welander disease.

Abstract
In an attempt to understand the specific effect of inorganic protein denaturants, lithium cation and perchlorate anion, upon the molecular conformation of bovine alpha-lactalbumin and to characterize the denatured states of the protein and the denaturation processes, themodynamic studies on the reversible unfolding of the protein in the presence of lithium chloride, lithium perchlorate and sodium perchlorate were made by means of circular dichroism and ultraviolet absorption measurements. The denaturation reaction caused by lithium chloride was found to take place in a three-state type, while that caused by the two perchlorates in a two-state type. The latter produces the same denatured state as the acid does on the protein, the state where the helical structures remain unchanged. The former produces two kinds of the denatured state, one being a less unfolded state than the acid denatured one and the other a fully unfolded state which is identical with the finally denatured state induced by organic denaturants such as guanidinium chloride, guanidinium thiocyanate and urea.
