During the past decade, there have been numerous direct and indirect scientific contributions to both the etiology and therapy of aplastic anemia and related bone marrow failure syndromes. Clinical observations, such as autologous bone marrow recovery after conditioning with immunosup pressive agents for bone marrow transplantation; failure to achieve en graftment in some identical twins without prior immunosuppressive ther apy; and hematologic response to immunosuppressive agents, have led to the concept of immune-mediated etiology of acquired aplastic anemia. Such a concept was further strengthened by laboratory findings, implicat ing the role of activated cytotoxic T lymphocytes and abnormal produc tion of inhibitory lymphokines. The immunologic mechanisms may also apply to the idiosyncratic bone marrow aplasias associated with drugs, toxic chemicals, and viruses. These agents may alter normal cellular recog nition sites by interacting with cellular components and result in loss of self tolerance. Immunologic mechanisms have long been advocated in many other organ failures, and the hemopoietic organ is no exception. It is of interest that parallel clinical and laboratory investigations in juvenile diabetes mellitus type I and in rodent models of this disease have yielded results compatible with the same pathogenic mechanisms. The infiltration of pancreatic islets by activated T lymphocytes, functional and morphological alterations of islet cells upon incubation with lymphokines such as gamma interferon and tumor necrosis factor, and clinical response to cyclosporine are a few examples.

Perkembangan fisik motorik anak adalah salah satu perkembangan yang penting dalam tahap usia dini. Dimana seharusnya guru dan orang tua bekerjasama untuk mengembangkan motorik tersebut. Guru dan orang tua harusnya menstimulus anak dengan berbagai permainan yang menyenangkan dan menumbuhkan rasa senang terhadap anak, agar anak tertarik untuk memainkannya, dan yang paling penting dengan melakukan permainan tanpa disadari anak telah mengembangkan motoriknya. Perkembangan fisik motorik merupakan proses yang dimana seseorang berkembang melaui respon yang menghasilkan suatu gerakan yang berkoordinasi, terorganisir dan terpadu. Maka keterampilan motorik dapat dilihat sebagai landasan seseorang berhasil dalam melakukan keterampilan motorik. Motorik yang terbagi menjadi motorik halus & kasar. Motorik kasar yaitu gerakan yang menggunakan otot besar dan membutuhkan banyak tenaga seperti, berlari, berjalan dan melakukan lompatan. Sementara motorik halus yaitu suatu gerakkan tubuh yang menggunakan otot kecil, dan memerlukan konsentrasi antara mata dan tangan, seperti, melipat, menggunting dan meronce. Buku ini disusun sebagai bahan bacaan atau referensi untuk pembaca bagi yang ingin mengembangkan kemampuan motorik anak usia dini. Harapannya dengan adanya buku ini dapat menjadi salah satu bahan rujukan atau literatur bagi para calon pendidik maupun orangtua. Buku persembahan penerbit PrenadaMediaGroup
