    Notes: 1. Effects of calcitonin on dopamine-, secretin- and pancreozymin-induced pancreatic secretion were investigated in the isolated blood-perfused canine pancreas.2. The volume of pancreatic secretion induced by pancreozymin given intra-arterially (i.a.) was decreased by an i.a. infusion of 1 u/min of calcitonin, but that induced by dopamine or secretin given i.a. was not affected by calcitonin treatment.3. Amylase concentration in pancreatic juice either in spontaneous secretion in the resting state or in that of stimulated secretion by pancreozymin was decreased approximately 30% by calcitonin treatment, but amylase concentration in pancreatic juice induced by dopamine or secretin was not affected by calcitonin treatment.4. Calcitonin had no effect on bicarbonate concentration in pancreatic juice stimulated by these secretagogues.5. Calcium concentration in pancreatic juice in the resting state was reduced about 36% by calcitonin treatment. Calcitonin caused a decrease in a calcium concentration in the pancreozymin-induced secretion, but did not cause any change in the dopamine- or secretin-induced one.6. These results suggest that calcitonin may affect the secretory mechanism of the acinar cells but not that of the ductular cells, and that the acinar cells are active even in the resting state.

    Notes: 1. The effects of glucagon on the secretion of pancreatic juice were investigated using blood-perfused canine pancreas preparations.2. Intravenous administration of glucagon (3–30 μg/kg) to the donor dog elicited a dose-dependent increase in pancreatic secretion. Intra-arterial administration of glucagon (10–100 μg) into the perfused pancreas also elicited increased secretion.3. There were slight increases in amylase concentration of the pancreatic juice with the largest doses of glucagon given by either route.4. Glucagon-induced secretion was not modified by treatment with phentolamine, propranolol, atropine, guanethidine, tetrodotoxin, haloperidol, prostaglandin F2a or calcitonin.5. The results suggest that glucagon acts directly on the exocrine cells of the canine pancreas.

    ANTIARRHYTHMIC PROPERTIES OF 5-(3-TERT-BUTYLAMINO-2-HYDROXY)PROPOXY-3,4-DIHYDRO-CARBOSTYRIL HYDROCHLORIDE (OPC- 1085), A NEWLY SYNTHESIZED, POTENT β-ADRENORECEPTOR ANTAGONIST (1977)

    Notes: 1. The antiarrhythmic properties of 5–(3-tert-butylarnino-2-hydroxy)propoxy-3,4-dihydrocarbostyril hydrochloride (OPC-1085) were compared with those of propranolol and pindolol using various kinds of preparations for experimental arrhythmia in dogs.2. Although OPC-1085 was the most potent drug to antagonize adrenaline-induced arrhythmia in animals anaesthetized with either pentobarbitone sodium or halothane, it was scarcely effective on ouabain-induced arrhythmia in pentobarbitone sodium anaesthetized animals.3. When these compounds were administered intravenously to conscious dogs 24 h after two-stage ligation of the anterior descending artery, ectopic ventricular beats of coronary ligation-induced arrhythmia were reduced while regular sinus beats were simultaneously increased.4. OPC-1085 was very effective on aconitine-induced arrhythmia in dogs anaesthetized with pentobarbitone sodium. The effective dose was similar to that of propranolol but about fifteen times less than that of pindolol.5. It is concluded that different potencies among these β-adrenoreceptor antagonists against various kinds of experimental arrhythmias cannot be simply deduced from any one of the following properties; β-adrenoreceptor antagonism, intrinsic myocardial stimulation, local anaesthetic and so-called quinidine-like effects.

    Notes: In this study, 30 dentists were surveyed about their methods of palpating teeth for the evaluation of premature contacts. Thirty-eight dentists were then tested to determine their ability to discriminate degrees of prematurity using each of two different methods of palpation. The degree of digital pressure used by each dentist during palpation was also measured. The majority of dentists chose the same method for palpation: a single forefinger overlaying the facial surfaces of the central incisors being evaluated. In the discrimination test, the majority of dentists were able to identify reliably occlusal interference of ≥50 μm regardless of the palpation method used.

    Deep impurity levels and diffusion coefficient of manganese in silicon (1991)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Manganese-related deep levels in n- and p-type silicon have been investigated by deep level transient spectroscopy and Hall effect. Two electron traps of Ec−(0.12±0.01) eV and Ec−(0.41±0.01) eV, and a hole trap of Ev+(0.32±0.01) eV are found in manganese-doped silicon. The energy levels of these traps correspond to the transitions between four charge states (Mn−, Mn0, Mn+, Mn++ ) of interstitial manganese. An additional donor-type electron trap of Ec−(0.51±0.02) eV is observed in the n-type samples, and the trap can be tentatively assigned to substitutional manganese. Furthermore, an electron trap of Ec−(0.50±0.02) eV is observed for n+p junction samples diffused with manganese in boron-doped p-type silicon. The trap is attributed to the manganese-boron complex, which is formed owing to the pairing reaction of interstitial manganese and substitutional boron. From the investigation of the pairing reaction, the diffusion coefficient DMn of interstitial manganese is determined in the temperature range 14–90 °C. It can be represented by the expression DMn=2.4×10−3 exp(−0.72/kT)cm2 s−1.

    Notes: We have studied the feasibility of using carbon as a scanning tunneling microscopy tip material for experiments conducted under electrochemical environments. The tips were found to be stable and durable in acidic or alkaline solution for several hours. The fabricated carbon tips were capable of resolving graphite atoms in electrolyte solution under potentiostatic condition as well as in air.

    Merkel cells in human fetal eccrine glands (1993)

    Notes: The presence of human Merkel cells in the eccrine ridges and eccrine germs was studied, using antibodies to simple epithelial keratins, in separated epidermal sheets with attached eccrine ducts. The localization of Merkel cells could be analysed three-dimensionally in the wet, whole-mount of the stained sheets. In the plantar skin of a 12-week-old human fetus, immunoreactive (ir-) Merkel cells were randomly located in the flattened epidermis. In the plantar skin of a 15-week-old human fetus, there was early development of eccrine germs, and Merkel cells were concentrated in eccrine gland ridges. In the plantar skin of a 20-week-old human fetus, eccrine germs were well formed and ir- Merkel cells were located within the developing eccrine ridges and ducts. In the plantar skin of adults, the eccrine concentration of Merkel cells was markedly reduced. Concentration of Merkel cells on the eccrine structures was also observed in the scalp skin of human fetuses. This tendency continued into adult life, although there was a marked reduction in the total number of Merkel cells. These findings suggest that epidermal Merkel cells move down into the eccrine ducts as eccrine germs extend into the mesenchyme. Alternatively, they may develop de novo from the keratinocytes of the eccrine duct. In view of the expression of nerve growth factor receptor in fetal Merkel cells, it is postulated that these eccrine gland Merkel cells play a role in the formation of the periglandular nerve plexus.

    Notes: The effects of 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) on the growth and DNA synthesis of cultured human keratinocytes obtained from involved and uninvolved psoriatic epidermis and normal epidermis were studied. Treatment with 10-8m and 10-7m of 1,25(OH)2D3 inhibited cell growth as follows: 58.5±19.3% and 21.3±13.6% in normal keratinocytes (n=6); 43.8±22.8% and 17.8±12.3% in psoriatic uninvolved keratinocytes (n=4); 51.7±18.2% and 13.2±6.4% in psoriatic involved keratinocytes (n=6). Inhibition was virtually complete at 10-6m. DNA synthesis was also inhibited by 10-8m, 10-7m and 10-6m of 1,25(OH)2D3 as follows: 70.0±8.3%, 59.0±6.8% and 16.7±4.0%, respectively, in normal keratinocytes (n=3); 78.5±13.5%, 51.5±25.5% and 24.5±21.5%, respectively, in psoriatic uninvolved keratinocytes (n=2); and 69.3±14.5%, 41.3±19.1% and 14.8±11.2%, respectively, in psoriatic involved keratinocytes (n=4). These results indicate that 1,25(OH)2D3 functions as a growth inhibitor for cultured human keratinocytes derived from both normal and psoriatic skin.
