Cough and other reflexes on irritation of airway mucosa in man.
Both human and animal studies show that irritation of airway mucosa elicits a variety of reflex responses such as coughing, apnoea, and laryngeal closure. Most of the information concerning these reflex responses were obtained in anesthetized conditions with little applicability to awake conditions. Various aspects of cough and other reflexes on irritation of the airway mucosa are discussed. Studies on awake humans showed that stimulation of the laryngeal mucosa with a small amount of distilled water during wakefulness causes elicitation of the expiration reflex, cough reflex, and swallowing reflex while other types of responses are scarcely observed. In addition, the duration of these responses is remarkably short. In contrast, the same stimulation causes more variant, prolonged, and exaggerated responses during a light depth of anesthesia. An increase in depth of anesthesia abolishes expiratory efforts such as coughing and the expiration reflex whereas the apnoeic reflex and laryngeal closure reflex are resistant to the depressant effect of anesthesia. Also, the respiratory reflex responses to airway irritation varied, depending on the site of stimulation: both laryngeal and tracheal stimulation cause vigorous respiratory responses whereas bronchial stimulation causes little or no respiratory responses. These results indicate not only that the types and magnitude of reflex responses is greatly modified by the central nervous state but also that the site of stimulation is crucial for determining the pattern of respiratory responses elicited by airway stimulation in humans.

Cytologic studies on so-called atypical epithelium of the protuberant lesions in the stomach.
Cytologic studies based on the observation of 32 atypical epithelial growths from 31 patients revealed the following characteristics: (1) The nuclei were usually elongated. The mean size of the major axis of the nuclei was most frequently distributed in the range of from 14 to 17mu while the mean size of the minor axis was between 6 and 10mu. (2) The chromatins of the nuclei were fine and showed even to somewhat dense distribution. The nucleolus was inconspicuous. (3) The cells were heaped together. A cellular aggregation was clearly composed of smaller groups of cells in which the polarity of nuclear arrangement was well preserved. Some cells at the periphery of a cellular aggregation were arranged radially toward the outside. The cells were usually cohesive, but in severe grade of atypism, they sometimes showed a scattering tendency. (4) The cells of atypical epithelium seemed to be very insensitive to radiation, compared with carcinoma cells of the stomach.

Studies on cytologic characteristics of mammary aspiration smears based on histologic types.
Cytologic findings of aspiration smears from 146 histologically confirmed mammary were analyzed in this paper. High cellularity, dispersal of cells in the smears and enlarged nuclei of more than 20 mu in major axis were considered to be useful key points to distinguish carcinoma from benign lesions. Irregular piling, variable nuclear shape, cellular fusion and cytoplasmic inclusions were other common findings in cancer specimens and were scarcely noticed in benign cases. However, in some papillotubular carcinomas the above mentioned characteristics were not so dominant. Scirrhous carcinomas sometimes presented small nuclei in the smears. In some fibroadenomas, the smears were occasionally very cellular and revealed dipersal of cells.
