The natural occurrence of Japanese cedar (Cryptomeria japonica; CJ) pollinosis has been reported in Japanese monkeys (Macaca fuscata), an appropriate animal model for developing antipollinosis therapies. However, there has been no study on the incidence of Japanese cedar pollinosis in monkeys. To evaluate the incidence of CJ pollinosis in Japanese monkeys, we investigated the presence of pollinosis symptoms among monkeys in a troop, and the response to CJ allergens in pollinosis monkeys. We examined the presence of pollinosis symptoms in 272 monkeys in a troop throughout the CJ pollination season (February to April). Of the 272 monkeys, 21 (7.7%) showed pollinosis symptoms during the CJ pollen season. Blood samples were taken from the 21 monkeys that showed pollinosis symptoms and were tested for the presence of immunoglobulin E (IgE) antibody for CJ allergens. All 21 monkeys with CJ pollinosis had anti-CJ IgE. Of the 21 monkeys, peripheral blood mononuclear cells (PBMC) could be taken from 12, all of which showed CJ allergen-specific PBMC proliferation. The incidence of CJ pollinosis in a troop was 7.7%. The monkeys with CJ pollinosis demonstrated specific IgE and PBMC proliferation for CJ allergens.

In this paper, we propose a new iterative algorithm to solve the blind deconvolution problem of MIMO-FIR channels driven by source signals which are temporally second-order uncorrelated but fourth-order correlated and spatially second-and fourth-order uncorrelated. In our new approach, to solve the blind deconvolution problem, we consider two stages: First, filtered source signals are extracted from the mixtures of source signals. Second, the source signals are recovered from the filtered source signals.

There has always been a strong market requirement for rewritable optical disk drive as a follow-on product to read-only and write-once type optical disks. Fujitsu h a s been researching magneto-optic recording technologies for rewritabe optical disk , and h a s developed a disk sub-system with initiative of the National Aerospace Laboratory (NAL) in Tokyo. The drive h a s a large storage capacity of 8.9 GB/spindle with a few seconds of access time. It can store data economically in a small floor space, and it can be used as a supplement or partial alternative to magnetic disk drives or tape library units. The subsystem will be used from the beginning of 1989. This paper explaines the drive technologies, support software as well as the application of this new subsystem at NAL.3.
