A series of studies on the venous olfactory test were perfoumed and the results were as follows: (1) Initial and terminal time of olfactory senses surveyed by venous injection of Alinamin(Vitamin B1 preparate) (a) Normal:9.3sec., 170sec.Hyposmia:11.1sec, 60, 5sec.so called Anosmia:13.9sec, 48sec.(the former:initial time, the latter:terminal time) (b) The longer terminal time was seen in more Sensitive olfactory mucous membrance.
(2) According to previous olfactory test, dysos- mia was classified into two groups, i.e., hyposmia and anosmia
Each of which, according that test, is classified into two subgroups, thus dysosmia is classified into four groups, from I-degree to IV -degree.
(3) According to the region of disturbance of sense of smell, olfactory disturbance is divided into three types;
(a) morphorgic type
(b) neurogenic type
(c) combined type A critical clinical study of each type was also performed.
(4) Olfactograph based on olfactory dilution test and venous olfactory test.(initial time, termi- nal time) was proposed.
(5) With the use of the authoir olfactory test, the process of healing of dysosmia could be divided into three types.From these results, it was con- cluded that a careful study of the healing process was helpful in evaluating the prognosis and therapy.
