摘要:
The invention provides a method of treating a patient having a reduced population of neutrophils following a myeloablative cancer treatment such as high dose chemotherapy. Following myeloablative therapy, a cell composition of at least 25% neutrophil precursors, i.e. promyelocytes, myelocytes, and metamyelocytes, is administered to the patient. Thereafter, the neutrophil precursors differentiate rapidly in vivo to replenish the supply of mature neutrophils for fighting infection. The method is used to reduce the neutropenic window between the time of myeloablative therapy and the time required for infused stem cells to proliferate and differentiate into mature neutrophils.

An enclosure for small animals, such as rodents, is described wherein the enclosure is constructed of various component parts. The component parts of the enclosure can be easily replaced when either damaged or destroyed, thus eliminating the need to replace the entire enclosure. The enclosure can also be rapidly assembled and disassembled without the need for any tools or mechanical ability. The enclosure's component parts may be constructed of any suitable thermoplastic material, wherein the thermoplastic material can be either opaque, translucent, or transparent.

A circuit and method for computing an exponential signal x.sup.g is provided. The circuit includes a logarithm converter which converts an input signal to binary word that represents the logarithm of an input signal x. A first shift register shifts the binary word in a bit-wise fashion to produce a first intermediate value; while a second shift register shifts the binary word in a bit-wise fashion to produce a second intermediate value. The shift registers may be implemented using multiplexers. The shifting operations are equivalent to multiplying the intermediate values by a factor which is a power of two. The first intermediate value is either added to or subtracted from the second intermediate value to produce a combined value. An inverse-logarithm converter converts the combined value to the exponential signal.

A support for boat oars to hold the oars in a fixed stationary and at rest position without the use of the rower's hands. The support is of particular use in a single sculling boat and consists of securing oar straps fastened to a bar. An overall riser rod assembly is formed by placing upper and lower riser rods on a connecting rod. The overall riser rod assembly is pivotally connected at one end to a plate attached to the bar and, at the other end, to a plate attached to a mounting bracket. The mounting bracket is fastened to the structure of the boat. The overall riser rod assembly can be adjusted in length to conform to various boats and rowers. The support is easily lowered to an out of the way location when not in use.

An E.sup.2 PROM redundant memory element is provided whereby faulty or improperly coded ROM or E.sup.2 PROM elements may be replaced by the user in-package. An address programming element including an E.sup.2 PROM floating gate device having a programmed mode, an unprogrammed mode, and an inhibit mode, may be programmed and erased in-package. Addresses received by the redundant memory element in addition to other inputs determine the mode of the floating gate device.
