Item 1. Security and Issuer.

        This is the first amendment to the Schedule 13D previously filed by the reporting person with respect to the securities of the Issuer set forth on the cover page hereto (the "Prior Filing"). This amendment is being filed in order to amend Items 2, 5 and 7, and the cover pages thereto, of the Prior Filing.

Item 2. Identity and Background.

(a)

No change except TOA Medical Electronics Co., Ltd., is now known as Sysmex Corporation ("Sysmex") with its principal executive office at 1-5-1 Wakinohama-Kaigandori, Chuo-ku, Kobe 651-0073, Japan.

Item 5. Interest in Securities of the Issuer.

(a)

The aggregate number of shares of Common Stock of the Issuer beneficially owned by Sysmex is 205,051. As a result of the disposition of shares of the Issuer by Sysmex, and additional shares of Common Stock issued by the Issuer, this represents 2.0% of the outstanding Common Stock of the Issuer (rather than 5.3% as reported in the Prior Filing).



(b)

Sysmex has sole power to vote and to dispose of all of the 205,051 shares of the Common Stock of the Issuer.



(c)

Sysmex sold 126,800 shares through registered broker dealers at market price from time to time through February 7, 2002 and March 25, 2002.



(e)

As of October 1, 1999 (based on information reported by the Issuer), Sysmex Corporation owned (and continues to own) less than 5% of the Issuer's Common Stock. As a consequence, from and after such date Sysmex Corporation has not been the beneficial owner of more than 5% of the Issuer's Common Stock.
